This paper was examined the durability properties of concrete using rapid cooling slag as fine aggregate for concrete. The results of experiments, concrete using rapid cooling slag showed that durability properties was equal to concrete using normal fine aggregate.

This study was evaluated fluidity properties on the performance of fiber dispersion of basalt fiber in mortar matrix as part of a basic study for development to fiber reinforcement mortar using basalt fiber. Results of assessment, fiber dispersion performance of of fiber reinforcement mortar using basalt fiber, showed that viscosity agent is more effective to improve the fluidity and fiber dispersion than superplasticizer.
