TL;DR: In this article, the authors investigated the effect of using steel fiber and silica fume on the properties of concrete and found that the use of steel fiber increased both the mechanical strength and the modulus of the elasticity of concrete.

TL;DR: In this article, the paving blocks based on two cement types were used to replace aggregate with waste marble, and physical and mechanical tests were performed on blocks so produced, and the cement type turns out to be an important factor.

TL;DR: In this article, the effects of both steel fiber and matrix strengths on fracture energy of high-strength concrete were discussed, and significant influences of matrix and fibre tensile strengths on the fracture energy and the characteristic length of concretes were noted.

TL;DR: In this article, the properties of cement-based mortars with vermiculite and silica fume were investigated at ambient and elevated temperatures, and the results indicated that expanded vermiculate aggregate is a good fire resistant material.

TL;DR: The use of fly ash lowers values of compressive strength, splitting tensile strength, elasticity modulus, abrasion resistance, freeze-thaw resistance, porosity and water absorption as discussed by the authors.
