The objective of this research is to develop the concrete flooring tile product from old asphalt road waste. The 6 ratios of Portland cement type1: coarse sand: old asphalt road waste: water reducer type A: tap water were designed including: 1: 5: 0: 0.02: 0.4 1: 4.5: 0.5: 0.02: 0.4 1: 4: 1: 0.02: 0.4 1: 3.5: 1.5: 0.02: 0.4 1: 3: 2: 0.02: 0.4 and 1: 2.5: 2.5: 0.02: 0.4 by weight. The concrete flooring tile casted with the compressive machine. The property tests followed the TIS.378 - 1988 (concrete flooring tiles). According to the result it was found that the 1: 2.5: 2.5: 0.02: 0.4 was the proper ratio of the concrete flooring tile. The increasing of old asphalt road waste in concrete flooring tile effected to decrease the water absorption and thermal conductivity properties. In term of the density and bending strength properties there were not many differences. The developed concrete flooring tile product from old asphalt road waste can use as same as the common concrete flooring tile product in market.

The objective of this research is to develop the precast adobe wall panel with high corrosion resistance and good thermal insulation. The ratio of Portland cement type1 clay rice husk ash straw rice husk waterproofed liquid and tap water was mixed and casted as same as the common concrete and reinforced by bamboo. From the results the proper prototype ratio of precast adobe wall panel was Portland cement type1: clay: rice husk ash: straw: rice husk: waterproofed liquid: tap water which equal to 1: 3: 0.3: 0.02: 0.02: 0.02: 0.4 by weight. The properties of the precast adobe wall panel prototype included density 1797 kg/m3 water absorption 16.70% bending strength 2.61 MPa compressive strength 21.40 MPa thermal conductivity coefficient 0.314 watt/m.Kelvin. Moreover the precast adobe wall panel prototype also was verified by TIS.2226-2548 with properties of impact resistance deflection and hardness in medium duty (MD) level. These straw and rice husk effected the precast adobe wall panel to decrease the density bending strength thermal conductivity coefficient and increase the compressive strength and water absorption.

This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine rice hush-bark 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 rice hush-bark ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials

This research presents a study of the compressive strength flexural strength coefficient of permeability and superplasticizer requriment of Porous Concrete containing fine fly. Portland cement (CT) is partially replaced with pozzolans 0 20 30 and 40% by weight of the cementitious materials. The results show that the high compressive strength flexural strength and low total void ratio of Porous Concrete improves substantially with partial replacement of Portland cement with fly ash. Porous Concrete mix cement containing 20 and 30% of fly ash can be used to make cementitious materials. In addition the use of fly ash produces Porous Concrete mix with good compressive strength flexural strength total void ratio and coefficient of permeability.

This research project aim to develop method for analysis of gamma-oryzanol in rice bran with environmental friendly solvent. The total content of gamma-oryzanol in rice bran was investigated using the combination between partial extraction method with ethyl lactate solvent and the study of factors on partial extraction. The parameters that effect the amount of gamma-oryzanol with partial extraction method consist of weight of rice bran volume of solvent and extraction time were conducted. The result shown the maximum content of gamma-oryzanol that extracted with 50 milligrams of rice bran 5 milliliters of ethyl lactate and 2 minutes of extraction time. The quantity of gamma-oryzanol in rice bran that observed using partial extraction method with ethyl lactate solvent and classical extraction method were 4.23 and 4.32 milligram per gram rice bran respectively. The results from both extraction methods were well agreement. When the extracted rice bran was separated with High Performance Liquid Chromatography the result shown the main compositions of extracted rice bran including cycloartenyl ferulate 24-Methylene cycloartanyl ferulate and campestanyl ferulate. The develop method for analysis of gamma-oryzanol in rice bran using partial extraction with ethyl lactate solvent is easy use only small apparatus in laboratory cheap short-time consuming and use environmental friendly solvent.
