Description
The purpose of this research project is to compare the strength and durability
characteristics of rice husk ash-modified concrete with those of normal concrete in
the marine environment. Specimens prepared from concrete mixes with watercementitious
ratios of 0.40 and 0.55, and rice husk ash content of 0%, 10%, and 20%
were tested. The rice husk ash used was obtained from Agrilectric, power plant
located in Lake Charles, Louisiana. The grinding of the ash to particle size of 7-J..tm
to 45-J..tm was done by Process Research ORTECH Inc., Ontario, Canada. Strength
and durability tests were performed, following ASTM (American Society for Testing
and Materials) Standards. The significant fmdings are that the properties and quality
of the rice husk ash-modified concrete are as good, if not better than normal concrete.
