Abstract
Curing is an important parameter on the strength and durability development of concrete floors. Appropriate curing leads to the concrete strength gain, decrease in surface scaling and increasing the surface abrasion resistance of concrete. In this paper, the effects of a curing agent based on lithium polysilicates were investigated in an experimental program to verify their mechanical and durability properties. To this end, the compressive strength, water absorption, permeability under water pressure and abrasion resistance tests were carried out on the reference and cured specimens with curing agent. Based on the presented results, the compressive strength of air-cured and lab-condition specimens decreased more than 60% and 20% respectively. However, the specimens cured with Lithium Polysilicates agent lead up to 10% decrease in concrete strength. Moreover, the water absorption of specimens cured in air increased more that 3 times. The results showed that by application of such curing agents, the abrasion resistance increased by 8% in comparison with the standard curing system.
