Abstract

Because of the transformation of the load of an arrangement on the building infrastructure can receive the load outside the original plan, for that it is necessary to strengthen the structure so that the structure of the building remains safe. In this study the use of woven &non-woven fibers in new concrete is expected to increase strong press, strong tensile and modulus elasticity to conventional concrete. The mix design of the study uses the American Concrete Institute (ACI) method. The test sample of 36 was then divided into 3 variations. The results of this study have shown the addition of strong press, strong pull, and modulus elasticity. Strong press for woven increased 29.485% % and non-woven increased 7.296%, strong pull for woven increased 24.633% and non-woven increased 5.285%., modulus elasticity for woven increased 20,924% and non-woven increased 9.356%. For the comparison of both materials, woven is stronger than non-woven.

Abstract

This study aims to determine the value of compressive strength, split tensile strength, flexural strength, and modulus of elasticity in normal quality concrete with variations of coconut shell and nickel slag added materials in coarse aggregate. Making test objects in the form of cylinders 150 mm x 150 mm x 300 as many as 27 pieces and beams 150 mm x 150 mm x 600 mm as many as 9 pieces. The results showed that the addition of coconut shells and nickel slag to coarse aggregate for testing concrete with a mixture of 30% nickel slag and 20% coconut shells obtained values for the 28th day of compressive strength, namely 30,841MPa, 31,124MPa and 31,690MPa, strong Split tensile strength is 3,114MPa, 3,468MPa and 3,255MPa, respectively, the flexural strength values are 4,383MPa, 4,018MPa and 3,930MPa, respectively. And for the modulus of elasticity, the values obtained are 12763,274MPa, 15404,333MPa, and 13619,275MPa.
