This study aims to examine the effect of recycled Polyethylene Terephthalate (PET) artificial aggregate as a substitute for coarse aggregate on the compressive strength and flexural strength, and the volume weight of the concrete. PET plastic waste is recycled by heating to a boiling point of approximately 300°C. There are five variations of concrete mixtures, defined the percentage of PET artificial aggregate to the total coarse aggregate, by 0, 25, 50, 75 and 100%. Tests carried out on fresh concrete mixtures are slump, bleeding, and segregation tests. Compressive and flexural strength tests proceeded based on ASTM 39/C39M-99 and ASTM C293-79 standards at the age of 28 days. The results showed that the use of PET artificial aggregate could improve the workability of the concrete mixture. The effect of PET artificial aggregate as a substitute for coarse aggregate on the compressive and flexural strength of concrete is considered very significant. The higher the percentage of PET plastic artificial aggregate, the lower the compressive and flexural strength, and the volume weight, of the concrete. Substitution of 25, 50, 75 and 100% of PET artificial aggregate gave decreases in compressive strength of 30.06, 32.39, 41.73 and 44.06% of the compressive strength of the standard concrete (18.20 MPa), respectively. The reductions in flexural strength were by respectively 19.03, 54.50, 53.95 and 61.00% of the standard concrete's flexural strength (3.59 MPa). The reductions in volume weight of concrete were by respectively 8.45, 17.71, 25.07 and 34.60% of the weight of the standard concrete volume of 2335.4 kg/m3 Doi: 10.28991/cej-2020-03091626 Full Text: PDF

This paper aimed to assess the potential of using limestone dust to replace sand at levels of 0, 20, 40, 60, 80 and 100% by weight. Concrete mix design for cement : fine aggregate : coarse aggregate was 1: 2 : 4 and 0.40, 0.50, 0.60 water-to-cement ratios were used. The study started by testing the basic properties of the material. The compressive strength test was done with curing for 7, 14, 21 and 28 days and modulus of elasticity of concrete at 28 days, after which the microstructural properties of concrete modified with limestone dust were investigated. The study found that the concrete had better workability when increasing the limestone dust content. The incorporation of 40% limestone dust at 0.50 water-to-cement ratios was found to improve the compressive strength of the concrete and resulted in the maximum compressive strength. However, high levels of replacement lead to porous microstructures. Moreover, the use of limestone dust in concrete production tends to be more cost-effective. Therefore, the results of this research seemingly provide confirmation and support for the utilization of these waste materials by reducing the use of natural resources. Further, it is a goal of local governments to help promote the value of limestone dust for future use.

In the current era of globalization, the development of concrete in the construction sector is very rapid, be it housing, offices, bridges, roads, dams, ports, and others. That is inseparable from the use of concrete as a part of building construction. The use of coarse aggregate for concrete mixes, namely natural stone, is a non-renewable natural resource. Therefore an alternative is needed as a substitute. One of the natural resources that can be renewed is hazelnut skin. Candlenut is a traditional plant that has various benefits, one of which is a candlenut shell. In this study, the materials used for standard concrete mixtures consist of water, cement, fine aggregate, and coarse aggregate. The water used for mixing the concrete is taken from the PDAM channel. The results showed that the effect of candlenut shells used as a substitute for some coarse aggregate decreased compressive strength results from the results of standard concrete compressive strength. The results obtained by the value of standard concrete compressive strength at 28 days of concrete were 27.19Mpa for concrete using Candlenut shells of 20% produce a compressive strength value of 17.33 Mpa at 28 days of concrete. 35% produce a concrete compressive strength value of 16.04 Mpa, while 50% produce a concrete compressive strength value of 15.17 Mpa. Thus the research shows that more and more candlenut shells are being used as a substitute for coarse aggregate in the concrete mixture.

Waste Concrete

About 30% of the ceramic production all over the world considered as waste. This huge amount of ceramic waste can be recycled in the construction industry, especially in concrete mix design, which is the main scope of this research. Ceramic wastes could provide many advantages rather than sustainability. It is considered economical and can replace cement, coarse aggregate, and fine aggregate, such as sand. In this study, several concrete mixtures were designed according to the ACI standards to assess the ceramic waste concrete for fresh and hardened properties in terms of slump, concrete compressive, splitting tensile and flexural strengths. Six mixes included with 0%, 10%, 20%, 30%, 40% and 50% replacement of coarse aggregate by crushed ceramic waste. By comparing the results between ceramic waste concrete and conventional concrete specimens, the optimum mix design was found to be at 30%-coarse aggregate replacement. Scanning electron microscope tests performed on the concrete specimens to examine the bond between the particles, the porosity, and the elementary composition of the specimens. The percentage of savings in cost estimated when using the optimum mix design (30% coarse aggregate replacement) was about a 30% reduction in the construction cost per the Egyptian market.

<p class="Abstract">The development of technology construction has reached a period of caring for the environment. Many things been developed to support environmentally friendly construction. Itcan be started from the use of a mixture of natural ingredients into a mixture of construction materials. Concrete is a construction material that is often used in Indonesia, given its ease, price, and durabilityAlong with the development of the concrete periods has experienced many advances, one of which is in the drafting of a combined mix of making concrete, and to supporting environmentally friendly concrete, a mixture of natural materials are used as one of the making material of concrete.South Sumatra is one of the islands in Sumatra, which has an abundant plantation of rubber. The large number of rubber plantations makes rubber waste more and more, one of which is rubber seeds. Therefore it is necessary to treat rubber seed waste in order to reduce the amount of rubber seed waste and can be used to improve the economy of the surrounding community.  The rubber itself has many advantages in the industrial field. Utilization of rubber has been widely used, but no one has used rubber seeds as an aggregate substitution material in making a concrete without other chemicals. Therefore this research will discuss the rubber seed mixture as a substitute for coarse aggregate. The material used to make concrete is portland type I cement, coarse and fine aggregate from the Tanjung Raja area, and the rubber seeds used are from the Sembawa area. Coarse aggregate substitution using a mixture of rubber seeds  5%, 10%, 15%, and 20% were tested during the age of concrete of 7 days, 14 days, and 28 days.. The compressive strength of rubber seed substitution with a percentage of 5% shows the most significant compressive strength value of 19.33 Mpa. From the test results of this study it can be concluded that the greater the use of rubber seeds, the lower the compressive strength.</p>

This paper presents the behavior of concrete properties by replacing the conventional coarse aggregate used in the concrete mixture by two types of lightweight aggregate; Expanded Perlite Aggregate (EPA) and Volcanic Pumice (VP). To fulfill this aim; three laboratory tests were applied; density, compressive strength, and abrasion resistance, that conducted to extrapolate the range of the changes in the properties of concrete with existence those types of aggregate in the mixture. Also, the volumetric proportion adopted as a strategy for replacing the coarse aggregate by EPA or VP in the concrete mixture. Then, the volumetric proportion ranged from 10% to 50% with the variation step was 10%. Therefore, ten concrete mixtures are prepared and divided into two groups; each group contains five concrete mixes to represent the volumetric replacement (10-50)% of conventional coarse aggregate by EPA or VP. On the other hand, one extra mixture designed by using conventional aggregate (coarse and fine aggregate) without any inclusion of EPA or VP to be considered as a reference mixture. The obtained laboratory results of this study proved that the density, compressive strength, and abrasion resistance readings of concrete decreased at any volumetric proportion replacement of coarse aggregate by EPA or VP. The decrease in density and compressive strength of concrete readings amounted the peak level at 50% replacing of coarse aggregate by EPA, which were 38.19% and 77.37%, respectively than the reference mixture. Additionally, the compressive strength is an important factor affecting the abrasion resistance of concrete mixture, and loss of abrasion decreased as compressive strength increased.

Initial Idea

Title: The Effect of Using Mediteran Soil as Cement Substitution Materials in Compressive Strength and Tensile Strength of Concrete Concrete is a composite material (mixture) of cement, fine aggregate, coarse aggregate, and water. The potential of limestone in Indonesia is very large, reaching 28.678 billion tons which is the main ingredient in the cement manufacture. In the long run it will be depleted because it is a non-renewable natural resources. So to reduce the use of limestone the utilization of Mediteran soil as a substitution for some cement in the manufacture of concrete is required. The initial idea is based on the chemical composition contained in the Mediteran soil almost identical to the cement, which is carbonate (CaO) and silica (SiO2). The purpose of this research is to reveal the influence of substitution of Mediteran soil by 20% and 40% in the compressive strength and tensile of the concrete at age 3, 7, 14, and 28 days with the number of test specimen each 3 pieces on each variation in 10cm x20cm cylinder with planning of concrete mixture refers to SK SNI method T-15-1900-03. The type of research used is quantitative with the experimental method of laboratory test and data analysis of comparative method and regression. The results show that compressive strength and tensile strength of concrete using Mediteran soil substitution comparable to  the strength of normal concrete with dry treatment. In the composition of 20% Mediteran soils decreased by 51.35% or 7.9 MPa (compressive strength) and 30.60% or 0.93 MPa (tensile strength). While the composition of 40% Mediteran soil decreased by 43.78% or 9.13 MPa (compressive strength) and 2.24% or 1.31 MPa (tensile strength).

The Impact

In order to study the static and dynamic mechanical characteristics of the coal gangue concrete used in the mine support structure, the compressive strength test, the drop weight impact test, and the Split Hopkinson Pressure Bar (SHPB) test were conducted. The compressive strength, initial and final impacting energy, dynamic strength, and failure characteristic of concrete were obtained of the concrete single-doped with coal gangue coarse aggregate, single-doped with coal gangue fine aggregate, and codoped with coal gangue coarse and fine aggregates. The results show that (1) it is feasible that employing coal gangue to replace natural coarse and fine aggregates in concrete can prepare C30 and C40 concrete; (2) the addition of coal gangue fine aggregate has a positive effect on the impact energy of the initial and final cracks of concrete, while the addition of coal gangue coarse aggregate has a negative effect on it; (3) compared with the static strength, the dynamic strength of concrete is improved no matter whether coal gangue is added to concrete; (4) the incorporation of coal gangue coarse aggregate will make the concrete shear surface smooth; (5) at the given impacting pressure, the concrete with coal gangue coarse aggregate has greater particle breakage and those with coal gangue fine aggregate has less. The research of this study can be a reference for the application of gangue concrete in mine support structures.
