PENGARUH PENAMBAHAN LIMBAH BETON DAN LIMBAH BATU BATA SEBAGAI PENGGANTI AGREGAT HALUS DALAM MENINGKATKAN KEKUATAN BETON

Concrete is a mixture composed of course aggregate (crushed stone and rock is not broken), fine aggregate (sand), cement and water with or without added ingredients. For development infrastruktur start from buildings, roads, and bridge using concrete, it demonstrates to the use of concrete in construction. Development of concrete technology required to meet the needs of the development. The more demand for the manufacture of concrete material to the depletion of the inventory of materials including fine aggregate ( sand ). The use of waste concrete and brick walls as a substitute for fine aggregate is expected to reduce the use of sand as a natural material. The concrete mix used with different variation, for determines the composition of the mixture compressive strength plan. The variations in the composition of the waste fractions concrete 10% and waste brick walls 90%, waste fractions concrete 30% and waste brick walls 70%, waste fractions concrete 50% and waste brick walls 50%, waste fractions concrete 70% and waste brick walls 30%, waste fractions concrete 90% and waste brick walls 10%.
