This research aims to produce scrap page kaolin of brick construction. The kaolin clay ratio of 100: 0 80:20 60:40 50:50 40:60 20:80 and 0: 100 by volume Add mixed with rice husk and rice 15 percent by weight A total of seven ratios. According to standard tests or TIS. 77-2545 ordinary story brick building. The moisture content and water absorption is increasing. While density Thermal conductivity resistance flexural and compressive strength tends to decrease. The best ratio of 80:20 by volume with compressive strength 43.16 kg / cm 2 and 24.93 percent water absorption. Criteria standard of TIS. 77-2545 requiring compressive strength not less than 35 kg / cm2 and water absorption must not be higher than 25 percent. Can be used in the manufacture of brick construction including building decorative wall can be developed into products. Because skin color and beautiful
การพัฒนาเถ้าหนักเป็นวัสดุมวลรวมในงานคอนกรีต
This research presents a study of the compressive strength chloride penetration and resistance to corrosion of concrete containing bottom ash. Fine and coarse aggregate is partially replaced with bottom ash 25 50 75 and 100% by weight of the aggregate. The results show that the compressive strength and low chloride penetration of concrete improves substantially with partial replacement of aggregate with bottom ash. Concrete mix cement containing 25 and 50% of bottom ash can be used to make coarse aggregate. In addition Concrete mix cement containing 100% of bottom ash can be used to make fine aggregate. The use of bottom ash produces concrete mix with good compressive strength and resistance to chloride and corrosion.

This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine fly ash and ground bagasse ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with fly ash and bagasse ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials. In addition the use of fly ash and ground bagasse ash produces Cellular Lightweight Concrete mix with good compressive strength tensile strength flexural strength and water absorption.

In this reseach propose developed method for reduction of corrosion of reinforcement in concrete using electrical electron theory (artificial anode). That is electrochemical reaction in the concrete with current electron of electricity designing interchanges galvanized steel by install zinc anode. Zinc is one of the first materials to be used in ion exchange processes easily. Properties of Electrica will include the anode (Anode) and specemen concrete is negative (Cathode). The system is effects to results; reduce superior resistance corrosion in reinforcing steel in concrete more the better then traditional. The relationship of the electric reduction in the reinforcement concrete depen on capable of zinc electricchamical reduction in the steel of reinforced concrete. Zinc anade size is use to install concrete corrosion rate in steel reinforcement is direct variation of size.
