Cement Testing

Introduction

Cement is a water-based binder used to bind other building materials together. It is used in the production of mortar and concrete during the construction process. The reason cement is one of the most common construction ingredients among other is its ability to hold the structure together. Compressive strength is one of the most important properties of concrete and mortar. The strength of the binder (cement) therefore has a significant effect on the performance characteristics of the mixture and ensures the overall quality of the finished product.
