The theoretical prediction of the cracking stress of glass fibre reinforced inorganic cement

Glass fibre-reinforced inorganic cement is increasingly being seen as a promising new building material. For any structural use, its cracking stress will be significant because of its resemblance to the yield point of mild steel. In this paper, the use of fracture mechanics to formulate a prediction of the cracking stress is proposed. Experimental evidence is also presented in support of this theory.
