Ground Clay Bricks With Blast Furnace Slag In Blended Cements As Ternary Blended System

Author(s): M.Heikal, H.El.Didamony and M.El-Shrief

This paper study the effect of substitution of two by-products, namely granulated blast furnace slag (WCS), from iron steel company and homra (GCB) from Misr Brick (Helwan, Egypt) by 30 mass% OPC on the physico-chemical and mechanical characteristics of the investigated hardened cement pastes. The required water of standard consistency and setting times were measured. The hydration kinetics as well as physicochemical and mechanical characteristics of the hardened cement pastes were investigated. Some selected specimens were tested by TGA, DTA and FT-IR techniques to investigate the variation of hydrated products of the prepared blended cements. The results showed that, substitution of OPC by 30 mass% WCS the initial and final setting times were elongated, whereas, increase of the amounts of GCB up to 30%, the setting time accelerates. Addition of 30% WCS (S1) to OPC, reduces the amounts of chemically combined water contents at all curing times. On the other hand, substitution of WCS with 10 mass% GCB, the chemically combined water increases at all curing ages. 30 mass% Homra (GCB) shows the lowest total porosity than these values of total porosity. 30 mass%, GCB the compressive strength increases and shows the maximum values than all hardened blended cement pastes. ï›™ 2006 Trade Science Inc. - INDIA
