Abstract This research paper highlights the Rice Straw Ash (RSA) which is an agriculture wastage from rice cultivation and milling processes can be utilized in construction work. Compressive strength is increased due to replacement of rice straw ash up to 12.5% and also 10% cement replacing, it also increases the initial and final settlement time of mortar. By replacing of 10% RSA, the compressive strength is step by step increased and also by replacing the cement ratio the property of mortar (Water permeability) is depended and so as age of mortar. We can simply describe it that, by increasing age and compressive strength of mortar the permeability is decreased. Permeability of RSA mortar depends on the cement substitution percentage of RSA and age of mortar. When the permeability decreases, the compressive strength of mortar also increases.

Blitar Regency is one of the strange culinary centers, among which are processed various foods from snail base ingredients, ranging from kripik, sate oseng-oseng and so on as well as the existence of Blitar district is one of the rice barns in East Java. With the existence of Blitar district as a snail-based culinary producer and one of the rice barns in East Java, this is not spared from several problems, such as the disposal of snail shells in the river and burning of rice straw in rice fields which both will cause environmental damage. This study aims to examine the use of snail shell ash and rice straw ash as a substitute material for cement in mortar mixtures against mortar compressive strength. The research method used was the experimental method by mixing fine aggregate main ingredients with snail shell ash and rice straw ash then testing the compressive strength. The results of the compressive test with the addition of the percentage of snail shell shell turned out to increase by 54.78%.

Compressive Strength Of Concrete

This paper presents the results of an experimental investigation of the compressive strength of concrete cubes containing termite mound soil. The specimens were cast using M20 grade of concrete. Two mix ratios for replacement of sand and cement are of 1:1.7:2.7 and 1:1.5:2.5 (cement: sand: aggregate) with water- cement ratio of 0.45 and varying combination of termite mound soil in equal amount ranging from 30% and 40% replacing fine aggregate (sand) and cement from 10%,15%,20% were used. A total of 27 cubes, 18 cylinders and 6 beams were cast by replacing fine aggregate, specimens were cured in water for 7,14 and 28 days. The test results showed that the compressive strength of the concrete cubes increases with age and decreases with increasing percentage replacement of cement and increases with increasing the replacement of sand with termite mound soil cured in water. The study concluded that termite mound cement concrete is adequate to use for construction purposes in natural environment.

To manage tyre waste and conserve natural aggregate resource, this research investigates the use of waste tyre rubber as partial replacement of fine aggregates in non-structural concrete. The research used Taguchi method to study the influence of mix proportion, water-to-cement ratio and tyre rubber replacement percentage on concrete. Nine mixes were prepared with mix proportion of 1:2:4, 1:5:4 and 1:2.5:3; water-to-cement ratio of 0.25, 0.35 and 0.40 and rubber to fine aggregate replacement of 20%, 30% and 40%. Compressive strength and water absorption tests were carried out on 100 mm cubes. Compressive strength was directly proportional to the amount of coarse aggregate in the mix. Water-to-cement ratio increased the strength within the range used in the study. Strength was found to be more sensitive to the overall rubber content than the replacement ratio. Seven out of the nine mixes satisfied the minimum strength requirement for concrete blocks set by ASTM. Water absorption and density for all mixes satisfied the limits applicable for concrete blocks. The study indicates that mix proportions with fine to coarse aggregate ratio of less than 1.0 and w/c ratio around 0.40 can be used with tyre rubber replacements of up to 30 % to satisfy requirements for non-structural concrete.

Concrete is a widely used material in all construction work. The aim of the project is to study the behavior of concrete with replacement of E waste. The fine aggregate and coarse aggregate are naturally available due to increase in demand it is over exploited. The waste utilization is sustainable solution to environmental problems Waste from electric and electronic equipment is used as an E waste replacement for coarse aggregate in concrete which is used in the construction .Therefore the effects have been made to study the use of E waste components as a partial replacement of coarse aggregate in 5%, 10% and 15%. To determine the optimum percentage of E waste that can be replaced for coarse aggregate the compressive strength and split tensile strength of concrete to be studied. After determining the optimum percentage of E waste that can be replaced with coarse aggregate. The comparison of the conventional and optimum percentage of E waste replaced with concrete has been done

The suitability of burnt and crushed cow bones (BCCB) as partial replacement for fine aggregate in concrete was studied. The percentages of replacements of fine aggregates of 0, 10, 20, 30, 40 and 50%, respectively of BCCB were tested considering 1: 2: 4 and 1: 11/2 :3 concrete mix ratios. The cow bones were burnt for 50 minutes up to 92oC before being crushed. Ninety-six (96) concrete cubes of 1: 2: 4 mix ratio and ninety-six (96) concrete cubes of 1 : : 3 mix ratio measuring 150x150x150mm were tested for the compressive strength at 7, 14, 21 and 28 days respectively. The research revealed that the BCCB acted as a retarder in the concrete. Water-cement ratio increased with the increase in the percentage of the BCCB. The mixes of 1:2:4 and 1::3 at 28 days curing yielded average compressive strengths in N/mm2 ranging from 16.49 - 24.29 and 18.71 - 29.73, respectively. For the mix ratios of 1:2:4 and 1:: 3 at 28 days curing age,  it was observed that increase in the BCCB content beyond 40 and 50%, respectively resulted to the reduction of the average compressive strength below recommended minimum strength for use of concrete in structural works.http://dx.doi.org/10.4314/njt.v36i3.4

Pvc Pipe

In the present research an attempt has been made to replace some part of fine aggregate (sand) by an industrial waste, the industrial waste under investigation is produced when the PVC pipes are cut into the desired sizes, it is a very thin flaky substance having a specific gravity of 1.5.This material is very voluminous in nature, so it reduces the workability of concrete if used in large percentage. So this material cannot be used in very large quantities but it can successfully replace sand up to 20 percent when used in pavement blocks. Experimentation was done at a water-cement ratio ranging from 0.43-0.35.Compressive strength of the concrete has been evaluated at 7 days, 14 days 21 days and 28 days. Results of the investigation indicate that compressive strength of the concrete decreases as the percentage of PVC waste material increases.7 day strength of the concrete has varied from 35.55 MPa to 70.01 MPa and 28 day strength has varied from 56.7 MPa to 76 MPa. Water absorption was well within the limits and varied from 4.67% to 7.26% by mass. The results revealed that this waste material can satisfactorily replace sand in small amount also it is a great way to dispose of the waste and hence is a step forward in the quest for a greener concrete.

In this study, crumb rubber was used to partially replaced fine aggregate in mortar mixture by 5, 10, 15 and 20 volume percentage (vol%) with untreated and NaOH-treated crumb rubber. There were three (3) different water-cement ratio used which are 0.45, 0.50 and 0.55. Thus, the total number of mixtures was 27. The mortars were tested for flowability, compressive strength, flexural strength and density. Based on the results, higher water cement ratio and percentage of crumb rubber replacement increased the flowability but lowered the density, compressive strength and flexural strength of the rubberized mortar. It was also discovered that the significant effect of water-cement ratio on the fresh and hardened properties of the rubberized mortar was due to the water content in the mixture. Meanwhile, the use of NaOH as treatment to crumb rubber improved the flowability, compressive strength and flexural strength of the rubberized mortar.
