“…Rice straw was collected from the Egyptian farms and prepared for the burning process by using a huge iron container designed at the bottom of a small room to light a fire with a Kerosene Stove shown in figure (1) for one day. RHA was ground by using a flour mill (ASSIUT /Walidia Street Mill) figure (2), then sieved with a standard sieve no 50mm.…”

“…The manufacture of rice husk ash to be used it in civil works as a partial substitute in concrete is not only a way to preserve the environment from the pollution but also to reduce the cost and improving the efficiency of concrete. Using RHA as a partial substitute for cement reduces the carbon dioxide CO2 air pollution produced from cement manufacturing (Djamaluddin et al, 2018). Rice husk ash is a highly pozzolanic reactive substance formed by controlled burning of rice husk (Bui et al, 2005).…”

Rice straw is one of the best sources of huge waste where governments try to get rid of it because it is harmful to the environment as the irregular burning of it by farmer's causes a lot of damage to the environment. This study aims to find the optimal dose of the plasticizer with the optimal replacement ratio of the Rice Husk Ash (RHA) and the optimum dose of superplasticizer (B-V-F) with ordinary Portland cement (OPC) concrete and comparing their results. Following is noted all researches agreed on the inevitability of using RHA without using a plasticizer, but no one studied the effect of added different doses of the plasticizer to RHA concrete or in other hand added it to different replacement percentages of RHA. In this study RHA generated by burning rice husk straw in a huge iron container for 24 hours. To improve pozzolanic activity, RHA was grinding in a flour mill. After the preparation of the material, we studied its chemical composition and physical properties. the Program consists of seven groups (A, C, A.13, A.15, A.2, A.1, and B) The first group mix (A) contained four mixtures of) OPC (by weight replacement (0, 10%, 15%, and 20%) from RHA, the second group contains six mixtures with a constant slump (15±3) and water-cement ratio (0.51), The first mixture is the control mix without any added of RHA or plasticizer the second mixture did not contain RHA, but it contained a dose of the plasticizer, the remaining four mixtures contained OPC by weight replacement Assessment of Using an Optimal Dose of Superplasticizer with the Optimum Replacement of Rice Husk Ash (RHA) on Concrete Compressive Strength

This study aims to an optimal dose of the superplasticizer (B-V-F) with the optimal replacement ratio of the Rice Husk Ash (RHA) and with ordinary Portland cement (OPC) and compares their results. This study generated RHA by burning rice husk in an appropriate iron container for about 24 hours. To improve pozzolanic activity, RHA was ground in a flour mill. The chemical composition and physical properties of RHA were studied. The experimental program consists of seven groups of concrete mixes with different doses of superplasticizer and replacement percentages of RHA. The first group mix contained four mixtures of OPC with different RHA weight replacements (0, 10%, 15%, and 20%). The second group contains six mixtures with a constant slump (15±3) cm and a water-cement ratio (0.51). The compressive strength of these mixtures was studded and compared with a control mixture (PURE OPC). The sixth group A.1 contains six mixtures with optimal RHA replacement (10%) of OPC with a constant slump of 23 cm, and different plasticizing doses were applied. The result shows that the optimum replacement of RHA was 10% which increased concrete compressive strength by about 32%. The optimal dose of superplasticizer with optimal RHA replacement (10%) was 15 L/m 3 which increased compressive strength by about 76%.
