Abstract |
This is an experimental study on the properties and the strength development of concrete using of the oyster shells as a substitute fine aggregate of concrete. For this purpose, the fundamental experiments of the materials and the main factors on it were considered and then the workability and many kinds of strength about the specimens were also studied. As the experimental results, there were strength differences of less than 10% between concrete with oyster shells and normal and the most excellent grain size of oyster shells is 5.0㎜ and less with taking uniformly and the percentage of practicable substitution of them to fine aggregate about 30%. This paper also represents the relationship equations among many kinds of strength and elastic modulus of concrete with the oyster shells decreased with increase in proportion of oyster shells and curve of it is similar about the percentage of substitution of 10%.
