Abstract

This research is a design and development of fly-ash to make concrete blocks for floor slaps to test the efficiency of the fly-ash floor slap concrete block strength according to the Thai Industrial Stand (TIS) 2035-2543 and to study the satisfaction of the consumers for the lignite fly-ash as a new floor slap concrete block. The research methodology was conducted by literature reviews, issue analysis by product designing experts, concrete block producers, concrete block distributers and consumers.  It was found that the producers, the distributors, the consumers were satisfied with the naturally designed products in the patterns of hibiscus, frangipani, fish and leaf.  For the beauty, the product colors were beautiful, new, different and eye-catching.  For the appropriateness in using the products includes ease for adjustment and placements and the efficiency of lignite fly-ash floor slap concrete block strength for the characteristics, pressure resistance and water absorption test.
