Thermal, Strength and Leachability Characteristics of Cellulose Fibre Reinforced Lime-Soil Brick

Abstract:

This research studies on the possibility of producing a more sustainable lightweight brick. Natural cellulose fibre produced from leaf and wood aggregates, lime and soil from local area of Thailand were added into the brick with minimizing Portland cement content. Effects of varied amount of cellulose fibre contents typically (10, 15, 20, 25, 30, 35, 40, 45, 50, 55 and 60 %) on mechanical and thermal properties of bricks are studied. Mechanical performances have been investigated with compressive, flexural strength and thermal conductivity of the samples. Also, the Leachate Extraction Procedure is observed. Results showed that adding more cellulose fibre contents can reduce the thermal conductivity, density including the compressive and flexural strength of the brick. On the other hand, the water absorption increases. It is also shown that the composite bricks can add fibre contents up to 55% by weight that can be used as non-load bearing concrete masonry units considered by the compressive strength. By conclusion, this application may be an interesting solution in order to improve sustainability and energy efficiency of the low cost house in local area of Thailand.
