Compressive Strength Of Concrete

One of the most important factors used to determine the compressive strength of concrete is its aggregate and matrix adhesion. This study examines the surface properties of polypropylene (PP) waste coarse aggregate (PWCA) to determine the influence of sand. The PWCA was made from the PP waste and different types of coating such as PWCA-R (river sand) and PWCA-V (volcanic sand), with experimental tests conducted on the physical properties of sand and PWCA, while the compressive strength, FESEM and density of polypropylene waste coarse aggregate concrete (PWCAC). Concrete specimens were prepared by replacing natural coarse aggregate with PWCA in percentages of 0%, 25%, 50%, 75%, and 100%, varying the water-cement ratio by 0.3 and 0.42 and using polypropylene (PP) waste coarse aggregate (PWCA-R and PWCA-V) as the coating material. The results showed that fineness modulus (F.M) and water absorption of the river sand was higher compared to volcanic sand. The PWCA-V had higher density and specific gravity compared to PWCA-R. On the other hand, water absorption of the PWCA-V was lower than PWCA-R. The PWCA concrete had density which varies from 1740 kg/m3 to 2074 kg/m3. For both, the PWCA concrete compressive strength at 28 days with a 100% replacement ratio was reduced by 43% to 55% compared to the natural coarse aggregate (NCA) concrete with 0.3 and 0.42 water-cement ratios. Also, the structural efficiency of PWCAC decreased with an increase in replacement ratio. River sand adhered to the PWCA surface resulted in a better compressive strength value compared to the volcanic sand.

Compressive Strength Of Concrete

Abstract: Compressive strength of concrete is the capacity of concrete to bear loads of materials or structure sans breaking or being deformed. Specimen under compression shrinks in size whilst under tension the size elongates. Compressive strength essentially gives concept about the properties of concrete. Compressive strength relies on many aspects such as water-cement ratio, strength of cement, calidad of concrete material. Specimens are tested by compression testing machine after the span of 7 or 28 days of curing. Compressive strength of the concrete is designated by the load on the area of specimen. In this research various proportions of such aggregate mixed in preparing M 30 grade and M 40 grade of Concrete mix and the effect is studied on its compressive strength . Several research papers have been assessed to analyze the compressive strength of concrete and the effect of different zones of sand on compressive strength are discussed in this paper.

Parent concrete coming from a wide range of sources can result in considerable differences in the properties of recycled coarse aggregate (RCA). In this study, the RCAs were obtained by crushing the parent concrete with water-to-cement ratios (W/Cparent) of 0.4, 0.5 and 0.6, respectively, and were strengthened by carbonation and nano-silica slurry wrapping methods. It was found that when W/Cparen was 0.3, 0.4 and 0.5, respectively, compared with the mortar in the untreated RCA, the capillary porosity of the mortar in the carbonated RCA decreased by 19%, 16% and 30%, respectively; the compressive strength of concrete containing the carbonated RCA increased by 13%, 11% and 13%, respectively; the chloride diffusion coefficient of RAC (DRAC) containing the nano-SiO2 slurry-treated RCA decreased by 17%, 16% and 11%; and that of RAC containing the carbonated RCA decreased by 21%, 25% and 26%, respectively. Regardless of being strengthened or not, both DRAC and porosity of old mortar in RCAs increased with increasing W/Cparent. For different types of RCAs, DRAC increased obviously with increasing water absorption of RCA. Finally, a theoretical model of DRAC considering the water absorption of RCA was established and verified by experiments, which can be used to predict the DRAC under the influence of different factors, especially the water absorption of RCA.

Recycled Coarse Aggregate

National effort to recycle construction waste as structural concrete usage of high economic value is ongoing, but performance rate of recycling is a low-level due to a lack of awareness on the recycled aggregates. Accordingly, the goal of this study was to verify the structural applicability of recycled aggregates. This study compared a compressive strength based on the replacement ratio of natural aggregate and recycled aggregate, and analyzed a correlation of wave velocity due to the increase in compressive strength under the same condition. The 『design standard strength – replacement ratio of recycled coarse aggregate』 was set to total 12 combinations by applying 0, 30, 50, 100[%] replacement ratio of recycled coarse aggregate to 21, 27, 35[MPa] to the design standard strength. During the experiment of fracture strength, strength degradation due to the replacement rate of recycled coarse aggregate did not occur, and it was found that the wave velocity also increased along with an increase in strength due to the age of recycled coarse aggregate concrete.

The strength characteristics of concrete made from different brands of cement used in Anambra State, Nigeria are reported in this paper. Samples of the selected brands of cement were collected and are used in mixing concrete. The study was conducted in Anambra State, Nigeria for 10 months. Samples of the selected brands of cement were collected and are used in mixing concrete. The fine aggregates used was obtained from River Sand (Onitsha), coarse aggregate is 12 mm quarried granite and water used for the concrete mixing is fit for drinking. These samples of concrete are tested in the laboratory (Anambra State Material Testing Laboratory) for workability and compressive strength and the result obtained were presented in simple tables The study found out that the compressive strength (28th day) of BUA, SUPASET, DANGOTE and UNICEM cements were 30.5, 31.70, 29.66 and 29.08 N/mm2, respectively. Also, the result of the slump value ranges from 70–140 (indicating that the concrete mix is workable) for all the four samples. The results indicate that SUPASET yielded the highest compressive strength (28th day) while UNICEM yielded the lowest compressive strength (28th day). The study was concluded by recommending that all the selected brands of cement within the study area met with the required standard. All concrete samples achieved the minimum compressive strength of concrete (i.e., 21 N/mm2) within 7 days of production. Though the popular cement in the study area is DANGOTE, SUPASET cement is the best cement in terms of strength characteristics while UNICEM possesses the least compressive strength.

Recycled concrete which are made by waste concrete has significance of environmental protection and saving natural resources. But there are different study results of recycled concrete of domestic and foreign scholars, so it is necessary to do the further study of recycled concrete. Compressive strength test of 225 concrete standard cube specimens have been done by Hydraulic Type Universal Testing Machine, and the relationships among recycled concrete compressive strength, age and recycled coarse aggregate replacement ratio have been studied. The results show: the growth rate of early strength of recycled concrete is smaller than natural concrete of the same gradation and the growth rate of later strength of recycled concrete is faster than natural concrete; when the recycled coarse aggregate replacement ratio increases the compressive strength of concrete decreases, and when the recycled coarse aggregate replacement ratio is over 70%, the decrease ranges more apparent.

Compressive Strength Of Concrete

It is proved that aggregate’s types have the severe effect on physicomechanical properties of concrete as aggregate covered almost 70 to 80 percent of the total volume of concrete. The effect of Flaky and Elongated aggregates on strength, durability, and workability of concrete has often been qualitatively expressed. The aim of this work is establishing the same quantitatively. M25 grade concrete for different ratios of weights of Elongated to normal aggregate, Flaky to normal aggregate and combined Flaky & Elongated aggregate to normal aggregate was tested for compressive strength at 28 days concrete. Three different types of aggregates were employed in the investigation, namely; normal aggregate, Elongated aggregate, and Flaky aggregate. Density and water absorption also kept constant to identify the effects on properties of concrete only for differences in shape. Thirty-six concrete cylinder was cast at 28 days. Varying dosages of Normal aggregate (60%, 65%, 70%, 75%,80% 85%), flaky aggregate (40%, 35%, 30%, 25%, 20%, 15%), elongated aggregate (40%, 35%, 30%, 25%, 20%, 15%), by mixture volume and length of 12inch (304.8 mm) & diameter of 6inch (152.4 mm) cylinder were used to test. Compaction was done by temping rod. Concrete cylinder was tested at the age of 28 days of curing. This study proposed of mixing three different types of aggregate in concrete. Compressive strength of concrete was measured by the effect of three different shapes of aggregates of varying dosages.

Fineness Modulus

ABSTRAKPersyaratan gradasi agregat kasar pada SNI dinyatakan dalam modulus kehalusan. Modulus kehalusan yang disyaratkan untuk agregat kasar adalah 6,0–7,1. Batasan gradasi agregat kasar yang ditetapkan dalam SNI seringkali tidak dipenuhi dalam pelaksanaan pekerjaan beton, terutama jika menggunakan agregat kasar berukuran 40 mm, yang mengakibatkan modulus kehalusan agregat kasar lebih besar dari 7,1. Perlu dilakukan penelitian lebih lanjut mengenai batasan gradasi agregat kasar untuk mengetahui pengaruh yang diakibatkan bila agregat kasar melampaui batasan rentang modulus kehalusan yang telah ditetapkan. Penelitian dilakukan dengan membuat campuran beton menggunakan cara Dreux untuk kuat tekan rencana 30 MPa, nilai slump rencana 30–60 mm dan 60–180 mm, serta modulus kehalusan agregat kasar 6,0; 6,5; 7,0; 7,5; dan 8,0. Hasil penelitian mengungkapkan bahwa campuran beton dengan modulus kehalusan agregat kasar di atas 7,0 tidak berpengaruh terhadap kuat tekan beton, maka batasan gradasi agregat kasar dapat dikembangkan dari 7,1 hingga 8,0.Kata kunci: batasan gradasi, modulus kehalusan, agregat kasar, kuat tekan beton ABSTRACT The requirements of coarse aggregate gradation in SNI stated with the fineness modulus. The fineness modulus required for coarse aggregates is 6.0–7.1. The limitations set in SNI are often not met in the implementation of concrete work, especially if using 40 mm aggregates, resulting in fineness modulus greater than 7.1. Further research on the coarse aggregate gradation limits is needed to determine the effects when it exceeded. The research is done by making concrete mixtures using Dreux's method with concrete compressive strength design  30 MPa, slump design 30–60 mm and 60–180 mm, as well as the coarse aggregate fineness modulus 6.0, 6.5, 7.0, 7.5, and 8.0. The results reveal that concrete mixtures with coarse aggregate fineness modulus above 7.0 do not affect concrete compressive strength, so the coarse aggregate gradation limitation can be extended from 7.1 to 8.0.Keywords: gradation limits, fineness modulus, coarse aggregate, concrete compressive strength
