Pinoy Builders Webinar – Role of Cement and Aggregates in Durability of Concrete

Concrete may seem basic at first glance, but a lot of thought is put into creating the right kind of batch for the project you are working on. Aggregates, mixing techniques, the weather – they all affect the quality in simple. but profound ways. Delve into the heart of concrete and see the science behind these simple, yet important building materials.
