The strength of any building mainly depends on the quality of the materials used. Concrete is a macro content. Even though we have tested its micro contents such as sand, cement, blue metal, and water. The mixing method and proportioning of the micro-ingredients may affect the strength of the concrete.
What do you mean Honeycomb in Concrete? Have you seen anything like the below on your site.? This is called as Honeycomb in Concrete. The surface looks very rough with voids and gaps between concrete and the reinforcement. It resembles like the honeycomb.
We have already discussed Nominal Mix of Concrete and Mix Proportions. If you have missed that please go ahead and read that. We will wait for you. It’s time for some calculations.
Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.
What is Nominal Mix and Design Mix ? and their Difference We hope you all know that Nominal Mix is site level mixing and Design mix are designed from RMC plant. You are right… But there are more than that.
