Description

Concrete floors can develop faults over time which can cause damage thus hindering smooth transportation, industrial aspects and some residential drawbacks. In addition, flaws and cracks are known to progress into more serious damage with time and use. Self leveling mortar has been used on a relatively limited scale worldwide to allow for more even, higher performance and easy-to-apply flooring. However, there has been little information available with respect to their use and best practices.

The primary focus of this work is to prepare mortar that possesses self-levelling flow characteristics. Hence, several mixtures have been designed using various constituents with moderate 28-day strength of 35 MPa. Chemical and mineral admixtures have been incorporated together with limestone to enhance the flow and cohesiveness as well as improve performance. The results reveal that self-levelling mortar can be successfully produced with comparable properties to ready-to-use market product. These mixtures were evaluated to have both performance and economic merits.
