COMPRESSIVE STRENGHT OF NATURAL STONE AGGREGATED CONCRETE WITH CURRING VARIATIONS OF SEA WATER, LONG WATER, AND RIVER AND GROUND WATER

Abstract

The increasing demand for housing today results in an increasing need for building materials as well. This raises concerns because of the depletion of raw material supplies, therefore to prevent it, modification of raw materials from waste is carried out which is one of the potential alternatives to be investigated, there are several factors that must be considered, one of which is the treatment of concrete (curing), many people do not pay attention to concrete treatment even though it is very easy, such as variations of soaking concrete with sea water, lime water, river water and groundwater, with water shortage areas being an alternative for concrete treatment. The data collection process is carried out through stages, namely literature study, field survey, laboratory testing and at the laboratory testing stage, sand, water, coarse aggregate and compressive strength testing are carried out. The results of the research on the compressive strength of the natural stone aggregate concrete of temples with curing variations of sea water, lime water, river water and ground water obtained the highest compressive strength of concrete with an average of 21.66 MPa of groundwater immersion while the lowest concrete compressive strength was immersed. lime water with an average of 18.66 MPa and for seawater the average compressive strength is 19.66 MPa while for river water the average compressive strength is 20.33 MPa and the results of the compressive strength of normal concrete are among them sea water 19 Mpa, lime water 20 Mpa, river water 20.666 Mpa, and ground water 22.666 Mpa the ratio of normal concrete to natural stone aggregate concrete temples, the compressive strength of concrete is higher than normal concrete for river water, groundwater and lime water, while for water immersion The compressive strength of the sea concrete with the natural stone aggregate of the temple is higher with the compressive strength of normal concrete.
