TL;DR
This paper reviews how admixtures and industrial by-products improve cement-based self-leveling mortar, promoting sustainability and performance in construction.
Contribution
The paper provides a comprehensive review of standards, additives, and industrial by-products in self-leveling mortar, highlighting sustainability and performance improvements.
Findings
China’s JC/T 985 standard offers more detailed testing parameters for CSL than the ISO standard.
High molecular weight additives improve the workability of cement-based self-leveling mortar.
Industrial by-product gypsum shows the greatest potential for application in green CSL.
Abstract
Cement-based self-leveling mortar (CSL) is a special building material that utilizes cement as the main cementitious component, combined with a variety of admixtures. Its self-leveling characteristics enable it to effectively level and fill uneven surfaces. Additionally, the innovative green CSL developed from industrial by-products can further enhance both environmental and economic benefits. This paper systematically reviews the use of admixtures and industrial by-products in the production of CSL. The main findings include the following: (i) compared to the international ISO standard, China’s standard JC/T 985 provides more detailed testing parameters regarding fluidity, mechanical properties, and shrinkage; (ii) the effect of additives on CSL is affected by its molecular weight and structure, and high molecular weight improving the workability of the additives; (iii) industrial…
