Block-yard equipment consists essentially of a means of moulding blocks, a concrete mixer and various general purpose tools and equipment. These are discussed below: Block-making equipment: If you mix the concrete yourself, you should use a mix design that yields a 30MPa concrete strength. Details of the mix design for this strength The theoretical calculations of the mix design procedures for concrete paving blocks have already been published elsewhere (Pani & Panda 2018). In this part of the research (Part II), experimental investigation will be carried out after developing three grades of concrete i.e. M30, M35 and M40 in the laboratory.Development of a Mix Design Methodology for Concrete Paving Blocks

Effect of mix design on compressed earth block strength
Trends in the effect of mix design on block strength reflect that strength increases with both moisture and cement content in the regimes of applicability for the production machinery. TheThe mix design variables included soil to sand ratio (SSR), water content, and Portland cement content. The soil type classified as silty-clayey sand according to the Unified Soil Classification System (USCS) and was held constant for all mix designs. Table 1 shows the specifications used for each mix design. Mixes 07, 08, 11, and 12 have “NEffect of mix design on compressed earth block strength
