Partial Replacement of Cement with Coconut Shell Ash in Sandcrete Block [PDF]

Research Journal of Applied Sciences, Engineering and Technology, 2018
In this study, Coconut Shell Ash (CSA) has been used to partially replace cement in Sandcrete Block (SB) manufacture in order to determine the quality of the SB produced in terms of compressive strength and durability. CSA has pozzolanic properties and as such, could serve as a partial replacement for cement and thus offset the cost of SB production ...
