Properties of clay-sand-rice husk ash mixed bricks

A total of 108 specimens were prepared to examine the hydraulic performance and strength performance of nine different cement-stabilized soils under unexposed and freeze–thaw exposed conditions. Sp...

Hydraulic and strength properties of unexposed and freeze–thaw exposed cement-stabilized soils

Cement-stabilized base (CSB), a cement-stabilized material for road pavement construction activities, generally has better essential properties than an unbound granular material, a commonly

Multivariate regression models in estimating the behavior of FRP tube encased recycled aggregate concrete

Two clay deposits from Lagos in Nigeria were used to develop cement-stabilized blocks. Crushing strengths were determined at the optimum water/cement ratios for different cement/clay-soil mixes which ranged from 5∶1 to 1∶15. The optimal cube crushing strength (Y
 2) decreased with increasing water/cement ratio (X) in a power relation as follows: Oregun Soil:Y
 2=16,329.29X
 −0.147. Alausa Soil:Y
 2=6,307.42X
 −0.580. Over 80% of the cube strength was developed by the fourteenth day (100% at 28 days). A comparison of the results with those of the British Statutory Minimum Compressive strength in bricks for various walls showed that the cement/clay soil mixes may be used for both load and non-load bearing walls of one or two storey houses.
