WebThis paper proposes the mixing design of concrete having modified sulfur-coated aggregate (MSCA) to enhance the durability of Portland cement concrete. The mechanical properties and durability of the proposed MSCA concrete were evaluated experimentally. Melting-modified sulfur was mixed with aggregate in order to coat the aggregate surface at a … Web70% sand, 30% cement, 80% sand, 20% cement. For each concrete batch, mix sand, cement, and water thoroughly, then pour into forms to make 3 bricks. Label each form with sand/cement ratio of concrete used. Allow the bricks to set overnight. Label each brick with sand/cement ratio used, then disassemble forms to remove the bricks.
