Abstract

The effect of temperature and slurry weight on compressive strength was investigated. Tests were conducted for 70, 80, 90,100 and 105 �F as well as slurry weights of 1.96, 1.98 and 2.0kg/l for test periods of 12, 24, 72 and 168hrs respectively. Test results indicated that compressive strength is a function of temperature and slurry weight, at a higher temperature and slurry weight respectively, compressive strength development is faster and vice-versa. Model coefficients were obtained using DATA FIT Engineering software and models which predict compressive strength with respect to temperature and slurry weight were developed. Results calculated from the model equation showed a good agreement with experimental values with less than 1% deviation. This will help predict compressive strength at different temperatures and slurry weights thereby saving time and rigour associated with actual laboratory pilot tests.
