Definition The gel space ratio in concrete refers to a measurement that involves calculating the ratio of the volume of the hydrated cement paste to the combined volumes of the hydrated cement and the capillary pores. Formula Of Gel Space Ratio The formula for calculating the Gel Space Ratio is: Gel Space Ratio = (Vw … Read more
Definition High strength concrete is a type of concrete that has a compressive strength exceeding 40 MPa. High strength concrete are significantly different from those of conventional or normal concretes. Description In order to produce High strength concrete, a more rigorous quality control process is required, along with careful selection and proportioning of materials. The … Read more
What Is Shrinkage Compensating Concrete? Shrinkage compensating concrete is used to reduce shrinkage in the concrete. Shrinkage compensating concrete contains a special type of expansive agent that compensates for the shrinkage that occurs as the concrete dries and hardens. Properties Of Shrinkage Compensating Concrete Advantages Disadvantages Applications Conclusion Shrinkage compensating concrete is a special type … Read more
Definition High density concrete is used in the construction of radiation shields. It is also called as heavy weight concrete. Explanation High density concrete is made by using natural heavy weight aggregates. The unit of heavy weight aggregates are 1.5 times higher than that of normal weight aggregates. The unit weights are in the range … Read more
Stress Strain Curve For Concrete Stress strain curve for concrete is used to understand and predict the behavior of concrete under various loading conditions. It is a graphical representation of the relationship between the stress applied to a concrete material and the resulting strain (deformation) that occurs. The stress-strain curve for concrete is typically divided … Read more

Introduction Of Concrete Retarder Concrete retarder is an external additives that retard the hardening of cement pastes and also delay the hardening of cement-containing mixtures such as mortar and concrete. Purpose Of Concrete Retarder Adding a retarder to a concrete mix can allow it to set up to an hour later. The hot climate causes … Read more
Introduction of Lean Concrete Concrete has a ratio of 1:3:6 or below is known as lean concrete. This is the ratio of cement, sand and coarse aggregate. Based on cement content, concrete can be classified as rich concrete and lean concrete. Rich concrete is used for structurul memebers while lean concrete is not for structurul … Read more
