The mechanical properties of the hardened concrete made of green sand and marble powder were studied at various ages. The microstructure and hydration products were also investigated to assess the impact of using green sand on marble powder as partial replacement for fine aggregate.Effect of green sand mixture with dextrin additives on ...Effect of green sand mixture with dextrin additives on mechanical properties of aluminum 6351 Kingsley Okechukwu Ikebudu 1, * , Swift Kenneth Onyegirim 2 and Philip Ifchukwu Udeorah 3 Department of Mechanical Engineering, COOU – Chukwuemeka Odumegwu Ojukwu University, Anambra State, Nigeria.INVESTIGATION MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ...microstructure and mechanical properties using green sand molding process done by other scientists and engineers. Therefore, in this part will discuss on white cast iron and its microstructure. Then, it is followed by mechanical properties and sand casting process. 2.2 METAL CASTING PROCESS
From 10 to 15% of the whole amount of molding sand is the facing sand. 2.5 Green sand. Green sand is also known as tempered or natural sand which is a just prepared mixture of silica sand with 18 to 30% clay, having moisture content from 6 to 8%. The clay and water furnish the bond for green sand. It is fine, soft, light, and porous.SAND, SAND ADDITIVES and SAND PROPERTİES Most green sand molds consist of silica sands bonded with a bentonite‐water mixture. The term green means that the mold, which is tempered with water, is not dried or baked. The composition, size, size distribution, purity, and shape of the sand are important to the success of the mold
