Efflorescence of Cement Mortar

Experimental Investigation of Toughness Enhancement in Cement Mortar

This paper presents the results of investigation carried out to improve the mechanical toughness of cement mortar. Toughness is a basic parameter which has to be improved in brick walls, concrete roads, machine foundations, dams etc. Materials fails due to an impact force and vibrations resulting in minor cracks and bonding failure between bricks, it leads to failure of the structure. In order ...

Influence of Pore Structure on Compressive Strength of Cement Mortar

This paper describes an experimental investigation into the pore structure of cement mortar using mercury porosimeter. Ordinary Portland cement, manufactured sand, and natural sand were used. The porosity of the manufactured sand mortar is higher than that of natural sand at the same mix proportion; on the contrary, the probable pore size and threshold radius of manufactured sand mortar are fin...

Utilization of waste glass as sand replacement in cement mortar

In this study, alkali silica reaction (ASR) expansion and strength characteristics of mortar containing waste glasses are analyzed in terms of waste glass content and glass color. Three different colors of waste glasses (white, green and brown) are replaced with sand at ratios of 10%, 30% and 100% by weight. The mixtures used in this study did not show a considerable ASR expansion. All batches ...

Rate Sensitive Behavior of Cement Paste and Mortar in Compression

Effect of Metakaolin on Strength and Efflorescence Quantity of Cement-Based Composites

This study investigated the basic mechanical and microscopic properties of cement produced with metakaolin and quantified the production of residual white efflorescence. Cement mortar was produced at various replacement ratios of metakaolin (0, 5, 10, 15, 20, and 25% by weight of cement) and exposed to various environments. Compressive strength and efflorescence quantify (using Matrix Laborator...
