The LWAGC was synthesized by the alkali activation of a fly ash (FA) as the source material by mixture of liquid alkaline activator. The resultant LWAGC possessed a compressive strength of 18.86 MPa at age of 28 days with oven-dry density of 1438.7 kg/m3. The Activator/FA mass ratio has been investigated at a range of 0.3-0.7, and shows a significant effect on the workability and compressive strength of the LWAGC. The results reveal that the activator content proposed by the standard mix design was at the optimum content level, since it provides a suitable workability for the fresh concrete and the highest compressive strength for the hardened concrete. The results demonstrated that the usage of an activator content, at levels either less or more than the suggested quantity deteriorated the properties of the resultant concrete. The significant result of the current study was to offfer proof of the reliability of the ACI 211.2-98 standard used for designing and mix proportioning of OPC lightweight aggregate structural concrete in the production of LWAGC. 2014-03-06T04:31:21Z 2014-03-06T04:31:21Z 2013-01 Article Advanced Science Letters, vol. 19(1), 2013, pages 282-285 1936-6612 http://www.ingentaconnect.com/content/asp/asl/2013/00000019/00000001/art00059?token=00501c50b2fb0fd535535c5f3b3b474666483f25737b74762f5f404f582a2f433e402c3568263c2b http://dspace.unimap.edu.my:80/dspace/handle/123456789/32388 en American Scientific Publishers All rights reserved. |
