Description	Journal: Iop Conference Series: Materials Science and Engineering A study was conducted on the effect of polycarboxylate ether superplasticizer on the mechanical properties of lightweight foamed concrete. This research focuses on the compressive strength, splitting tensile strength and flexural strength of lightweight foamed concrete using 0.5% and 1.0% polycarboxylate ether superplasticizer with targeted density of 1500 $kg/m^{3}$. Trial mix is carried out to determine the optimum water content for the 1:1 cement to sand ratio concrete mix. With optimum water content obtained, 7 days and 28 days samples are prepared and tested for both with and without polycarboxylate ether superplasticizer in compliance to ASTM standard. From the experiment, the optimum water content for 0.5% superplasticizer is 0.33 whereas the ratio for 1.0% superplasticizer is 0.30. The addition of superplasticizer yields best performance in all 28-days strength of lightweight foamed concrete. 1.0% addition of superplasticizer produces best result with 24.5MPa of compressive strength, 2.13MPa of splitting tensile strength and 9.49MPa of flexural strength. The addition of 1.0% superplasticizer makes the concrete mix fulfil the requirement of ACI 318 of structural concrete, which indicate the potential of mix in structural work.
