Abstract:
The early-age properties of low slump concrete and mortar with the strength accelerating compound were investigated. The strength accelerating compound was used as an additive and replacement material with varied content. The expansion of mortar samples containing the strength accelerating compound stored in water and the autoclave expansion of paste bar samples containing the strength accelerating compound were used to determine durability properties. The long term durability property such as sulfate resistance was also investigated. It was found that as consequence of using the strength accelerating compound as an additive material the earlyage compressive strength and slump of concrete were improved. The expansion of mortar due to storage in water was in the limit of the standard when incorporated with limestone powder. The autoclave expansion of paste bar sample containing the strength accelerating compound was less than 0.8%. The sulfate resistance of concrete was improved when using strength accelerating compound as replacement material.
