1. (a) The data presented below is compiled to obtain the modulus of rupture values of the MgO refractory brick. F = 7.0 x 10^4 N, L = 178mm, b = 114mm, h = 76mm Calculate the modulus of rupture. (b) Suppose there is an MgO fireproof brick with the same dimension and the same strength, excluding the height. The height is 64 mm. find LOAD (F) when it’s destroyed.

Masonry Units

Concrete masonry is among the most surplus building materials present since a wide range of aspects can be accomplished using Concrete Masonry Units (CMU) as they have more benefits than stone or brick masonry. CMU are manufactured in a variety of shapes, colors, sizes, and patterns for various functions and finishing. Due to their modular properties, different CMU can be mixed in the same wall for various textures, colors, and so on. For the formation of the concrete blocks, cement, aggregate, and water are required.
