Incorporation of Wastes from Marble to Produce Brick Materials
A brick material was prepared with marble wastes as main raw material by pressure forming and water-curing at room temperature. With the increases of the amounts of water additions, the compressive strength increased gradually and obtained a highest value of 34.8MPa in the sample of the ratio of cement: wastes=20:100 at 17.0% water addition, above which the strength had an adverse change and decreased. The addition of glass fiber had small effects on the strength, water absorbing rate and density comparing with that of wood flour. The strengths of sample had changed obviously with the increment of the forming pressures. However, the strength would fall because of the lamination caused by the recovering effects of the wood flour in the sample with replacement of the wood flour to marble wastes, as the forming pressures were higher than 5.0 MPa.
