Perbandingan Mutu Beton Memakai Campuran Agregat Batu Limbah Bangunan dengan Agregat Batu Kali (Penelitian)

Abstract

In daily life often found many old buildings that waste is very disturbing. Basically the building waste in the form of concrete fragments of a building can still be used as a partial replacement of coarse aggregate in concrete. Aggregate construction waste (concrete ex) as coarse aggregate, in addition to aggregate has technical properties, cheap, easily obtainable, and as an attempt to take advantage of building waste. Therefore the mixture of aggregate concrete with aggregate construction waste (concrete used) is expected to meet the criteria for the concrete mixture in accordance with technical requirements. Then the problem of this research is, large how maximum compression strength can be achieved by a mixture of aggregate concrete building waste (concrete ex) is. From the results of compression strength testing of concrete by using an additional aggregate of building waste (concrete used) by 15% by age 28 days, the compression strength obtained at 152.35 kg/cm2, or equal to the quality of K- 152 while the quality of K-175 planned . In the use of building waste (concrete used) as a mixture of concrete to be used as building material in the field, can be tailored to the needs of planning so as to achieve compression strength that meets the desired technical criteria.
