Artificial aggregate lightweight structural

Abstract

The need for lightweight concrete in a variety of applications of modern construction technology is increasing rapidly, the weight and compressive strength of structural lightweight concrete is 1,850 kg / m3, and the compressive strength of 17.2 MPa. Many methods are used to obtain lightweight concrete, including in this study conducting experiments to make structural lightweight concrete using iron wood waste, iron wood is made to replace rough aggregate by cutting iron wood into pieces and then coated with leak-proof without dropping paint followed by sprinkling sand while the paint is still wet. From the test results the weight and compressive strength at 28 days, concrete weight 1772 kg / m3, and compressive strength 17.99 MPa. From the results of strong and compressive strength tests using iron wood waste as a substitute for coarse aggregate, concrete using iron wood aggregate meets the standards as structural lightweight concrete. That the use of iron wood waste as a substitute for coarse aggregate in the way that we make can be an alternative as a substitute for coarse aggregate for making structural lightweight concrete. This material in addition to being used as material for making structural lightweight concrete can also help reduce waste.
