We characterized the effects of a biosurfactant derived from Pseudomonas fluorescens on slump loss, mechanical strength, capillary porosity, and bacterial colonization inside Portland cement-based mortar samples. Standard tests were used to evaluate the utility of this biosurfactant as an admixture. The addition of 1.5% biosurfactant increased the plasticity and improved the workability

The compressive strength of cement mortar cubes or concrete is one of the most important and useful property. The compressive strength of cement mortars is determined in order to verify whether the cement conforms to Indian Standard (IS, or other standards like ASTM, BS etc.) specifications and whether it will be able to develop the concrete of required compressive strength.

Mortar is a workable paste that binds building blocks together. It is made of cement and sand with different ratios to achieve the required strength. The compressive strength of mortar ranges between 2 to 12 N/mm 2. The mortar joints used in concrete block and brick construction are usually 10 mm thick.

Answer (1 of 2): Compressive strength of cement- sand mortar would depend on 1.) Grade of cement (43/53) 2.) nature of sand used (river/crushed sand which would have bearing on water requirement if no admixture is used for desired workability, if any) 3.) quantum of water 4.)

A high-strength concrete and mortar subjected to compressive fatigue loading were comparatively investigated using experimental and computational techniques. The focus of the investigations was on the influence of the coarse aggregate in high-strength concrete. Accordingly, the fatigue behaviour was analysed experimentally using the macroscopic damage indicators strain, stiffness and acoustic

For all cases, except for Type N mortar with a 5.1-inch flow, the compressive strength more than doubled when comparing cube strength to the typical mortar joint 3⁄8-inch-thick specimen strength. These results have significant implications related to the compressive strength of mortar in a masonry assembly.
