| Abstract | ||
| Light-weight concrete (LWC) has been successfully used since the ancient Roman times and it has gained its popularity due to its lower density and superior thermal insulation properties Compared with normal weight concrete (NWC).The main objective of the present study is to provide some information on properties of light-weight concrete using Yemeni light-weight aggregate, this study covers the use of light-weight coarse aggregate, two types of fine aggregates, superplasticizer and silica fume in concrete. The effects on density, absorption, compressive and splitting tensile strengths of lightweight concrete are reported. The resulting concretes were seen to have densities varying from 1420 to 1760 kg/m3, with the corresponding compressive strengths varying from 13.4 to 22.7 MPa .The results of absorption, show that the mixes containing superplasticizer and silica fume have lower levels of absorption compared to the mixes without admixtures. Further, the mixes made with light-weight fine aggregate have absorption values greater than that mixes made with normal fine aggregate. | ||
