Effect of Bentonite on the Performance of the Limestone Manufactured-Sand Mortar

Abstract:

In order to improve workability of manufactured-sand mortar, limestone manufactured-sand mortar mixed with bentonite, and discussed the role of different dosage of bentonite that had played on mortar fluidity, consistency, layered degree ,mortar compressive and flexural strength. The results show that, mortar water demand increases, fluidity, consistency, stratification decreases with increasing bentonite dosage. Bentonite can be good to improve the water retention properties of the mortar. Doped bentonite mortar strength improved, when doped with 0.9%, mortar has best water retention, flexural, compressive strength also reached maximum.
