The effect of expansive agent and cooling rate in the performance of expanded glass lightweight aggregate as an internal curing agent

Study on Replacement of Fine Aggregate with Light Weighted Super Absorbent Material in Internal Curing Concrete: A Review

“…To offer a competitive IC content and manage the drop in concrete strength, significant adjustments were made to the enlarged silicon carbide (SiC) composition and post-expansion cooling rate. [5] The optimal replacement ratio among RBP and cement is 5-15%, according to the available data. It is feasible to somewhat enhance the workability, mechanical qualities, and durability of cementitious materials by adding RBP in an appropriate amount (5-15%).…”

“…Cuevas Karla and Mauricio Lopez (2021) [5] Internal curing (IC) was provided by lightweight aggregate, which also lowers self-shrinkage and related cracking but may compromise strength. For the purpose of developing a superior IC agent, expanded lightweight glass aggregates (e.g., LWA) could be made and their properties enhanced.…”

“…These effects should be achieved by increasing the pore size during the grinding process. [5] Many issues, including the requirement to lower the cost of producing cement-based composites and the lack of disposal sites and environmental impact, can be effectively resolved by using RBP as a pozzolanic material. Its applications are thus extremely varied.…”
