Compressive strengths stated above were measured using cube samples. Test results obtained will vary if carried out to an alternative standard or sample dimensions are used. Note: Compressive strengths stated were measured at bottom end water, eg., the 28 day strength of 55 MPa for flowable consistency was obtained at a water addition of 3.6 litres of water per 20kg bag of Conbextra C.
