Sulphate Resistance of Concrete with Partial Replacement of Hydraulic Binder by Pozzolanic Material
Original language description
The object of the current study is to determine the manner in which ground fired bricks replacement of portland cement (OPC) in mortars influences the properties of the cement mortars, first of all sulphate resistance. The materials used in this study were two portland cements of different composition (higher and lower content of C3A), and two ground fired clay bricks of different composition ("acid" body and "lime" one). Replacement levels of OPC by ground bricks chosen for the tests were 10, 20, 30 and 40% wt. and the water to binder ratio (w/b) used was 0.50. Tested specimens were also characterised by measurement of pore structural characteristics. As a model sulphate environment 5 % wt. solution of Na2SO4 was used. Behaviour of specimens was characterised by determination of the expansion of specimens tested and by measurement of weight changes.
