الملخص الإنجليزي

In this research local raw materials are used in the preparation of concrete mixes.

Iraqi specifications (I.O.S) and American specifications (ASTM) are adopted, in determining the components of concrete, raw materials in different ratios weight of Kaolin (K) and MetaKaolin (MK) at a ratios of (5%, 10%, 15%, 20%) at different temperatures (150, 300 500 700, 900) ° C added to a mixture of concrete، to achieve the pozzolan interaction between [(K) or (MK)] and cement.

The mechanical, physical and pH effects by additions [(K) and (MK)], has been observed fixity of the compressive strength and tensile strength when add the rates ranging between (5% and 10%) of (MK) and a decrease of the ratios greater than (15%), the mechanical properties increased with increasing temperature of (MK), except for temperature less than (300) ° C.

The density has decreased by increasing the proportion added, but increased with increasing temperature.

The rate of absorption of water was observed that increasing the proportion of (MK) added, decrease the rate of absorption of water and also by increasing, the temperature of (MK), decrease the rate of absorption of water.

The percentage of water absorption decreased with the increasing temperature of (MK) and also increases the proportion of added (MK), decrease absorbance.

Also noticed, the acid of (MK) did not changing largely in the cement base in the concrete mix, especially in the grades more of the temperature (500) °C, and In general, observed staying concrete material within the limits of base material.
