Concrete Block Sizes and CMU Dimensions
Concrete Block Sizes and CMU Dimensions. For instance, a 6" CMU is nominally 6" deep. As with brick, CMUs have actual dimensions and nominal dimensions. The nominal dimension of a CMU is the actual dimension plus the width of the mortar joint. Typical CMU mortar joints are 3/8". The nominal dimension works within the 4" grid that other construction materials follow....
WHAT IS CONCRETE MIX DESIGN | CIVIL ENGINEERING
Dec 10, 2016· Requirements of concrete mix design. These mixes are termed standard mixes. IS has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2....
