Experimental studies on the utilization of kaolinite amalgamated in cement mortar

Received Date:17 May 2021, Accepted Date:20 August 2021, Published Date:21 September 2021


Objective: To investigate the physical and strength properties of mortar using locally available mineral admixture. Methodology: The compressive strength of the mortar at different temperatures was found. Setting time, consistency, and porosity were also studied by blending natural kaolinite and metakaolinite (MK) with cement in different proportions. An experimental work was carried out using control mix and adding kaolinite from 5% to 20% in ordinary Portland cement (OPC) at 5% equal intervals. Findings: The test results revealed that the use of natural admixtures such as Natural kaolinite (NK) and MK in OPC enhances the performance of the binder in mortar. The compressive strength enhancement of natural kaolinite cement–blended binder was comparatively lower than that of control mortar for all percentages whereas the mortar added to MK had increased strength. MK mortar with a 15% mix proportion was the optimum one to yield maximum compressive strength. Novelty: The present research work is focused on the partial replacement of metakaoline with temperature variant and the percentage of dosage used as a double variant parameter.
