INVESTIGATION ON ENVIRONMENTAL BENEFITS OF LOCAL RESOURCES FROM LOIKAW KAAH STATE
Abstract
- This research is preliminary proposing level to investigate how the addition of fly-ash affects the compressive strength of traditional bricks and the radon concentration of local resources. For this work dolomite, fly-ash and cement were used as raw materials to make brick samples. Before making bricks, they were analyzed by EDXRF and XRD techniques. Ten brick samples were prepared by dolomite and cement only without fly-ash as the ratio of 18:1(They have been currently used in Kayah State) and 6:1 in five of each. Other eight brick samples were prepared with different weight ratios of dolomite, fly-ash and cement. The compressive strengths of obtained bricks were determined by using Compressive Testing Machine (RBU-250). . From results the sample made by the mixture of dolomite, flyash and cement with the weight ratio of 2:1:1 shows the best compressive strength of 1325.59 PSI, which is significantly higher than that of traditional brick samples made by the mixture of dolomite and cement with the weight ratio of 18:1 (424.80 PSI). So that fly-ash (regional source) is an appropriate addition to make bricks with higher compressive strength. To study the radon concentration measurements in dolomite, fly-ash were examined by using LR 115 type II SSNTDs which were used as track recording materials.
