1 Year Long Term on Strength Properties of Pozzolanics Local Soil Bricks

Abstract:

This work emphasizes on the study of Pozzolanics Local Soil Brick properties. The compressive strength and flexural strength on modulus of rupture properties are investigated. At the ratio of 5% Portland cement type 1 and 30% fly ashes by weight at water powder ratio (w/p) 0.3525. This brick is called as Pozzolanics soil bricks. Their properties are compared to soil cement bricks (RCM35) at the age of 3, 7, 14, 28, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 and 360. Results show that the compressive strength and flexural strength increase with increasing curing time. The compressive strength and the flexural strength at 360 day curing times increases as 41.83% and 43.77%, respectively compared at 28 day curing times. Similar to soil cement bricks, the compressive strength and flexural strength of Pozzolanics soil bricks increase as 20.80% and 11.94% respectively compared between 360 day and 28 day curing times. However, comparing to RCM35 at 360 days the compressive strength and the flexural strength are lower as 60.43% and 4.90 times respectively.
