Enhance the properties of concrete using pre-developed burnt clay chips as internally curing concrete aggregate

摘要

Materials of internal curing concrete have been developed in many countries. Some of those Received 21 March 2019 materials are superabsorbent polymers, light weight aggregate (LWA), normal weight Received in revised form 31 August 2019 aggregate, recycled aggregate, bentonite clay, furnace slag and bottom ash. The most popular Accepted 6 September 2019 internal curing material is LWA. LWA are not available in most countries. Thus, the production of internal curing concrete (ICC) was limited for few countries. Consequently, this research was focused on the utilization of burnt clay chips as a new material to enhance the properties of ICC. Furthermore, water-cement (w/c) ratio and workability of ICC were investigated to develop high strength internal curing concrete (SICC). The water absorption and desorption.
