TL;DR: In this article, a new toughness index based on the load-deflection curve obtained in fracture tests is proposed, which is similar to the ACI toughness index but has the added advantages of being independent of specimen type and prescribed deflections.

TL;DR: In this paper, SBR- and EVA-modified concretes were prepared with various mix proportions and specimen sizes, and tested for compressive strength and drying shrinkage at various dry curing periods.

TL;DR: In this paper, an investigation into the use of kiln dust as a partial replacement for concrete was conducted and the results showed that it is a cementitious material and it causes the following effects when used as cement replacement: 1. 1. retards the setting of cement; 2. 2. increases the water demand for a constant consistency; and 3. 3. decreases the concrete strength.

TL;DR: In this article, the authors presented the results of an investigation conducted on steel fiber reinforced concrete beams in pure torsion, and the main parameters of the study were the volume fraction and aspect ratio of fibres.

TL;DR: In this paper, the results of a number of tests on deep fiber reinforced concrete beams are presented, which confirm that steel fibres can prevent shear failure in deep beams, and also indicate the various modes of failure of deep beams.

TL;DR: In this paper, both acoustic emission and ultrasonic pulse velocity measurements were used to try to monitor the structural integrity of concrete, and four different concrete mixes were each tested at ages up to two years to provide a wide range of concrete strengths.

TL;DR: In this paper, the bond between deformed reinforcing bars and both plain and steel fibre reinforced concrete under reversed cyclic loading was studied, and the results indicated that fibre additions increased the load level at which visible cracking first appeared, and tended to make crack growth more gradual.

TL;DR: In this article, the strength development of polyester resin concrete under various curing conditions was investigated and the results indicated that the compressive strength of the heat cured resin concrete is considerably high as compared with that of water and dry cured concretes.

TL;DR: In this paper, the authors describe the properties of polystyrene-bead concrete and suggest a method of mix design, which is used to form the cores of concrete sandwich beams and slabs.

TL;DR: In this paper, the influence of fiber reinforcement on crack propagation in concrete was studied by tests on large double torsion specimens, 48 inches long, 16 inches wide, and 2 inches thick (1220 x 406 x 51 mm).

TL;DR: In this paper, the effects of water-cement ratio, air content and heat curing on the properties of polyurethane composites were investigated, using saran, styrene-butadiene and acrylic latexes.

TL;DR: In this article, the flexural strength and fracture properties of a commercially produced wood fibre reinforced cement were studied and it was found that saturated specimens were 10-20% weaker than air-dry specimens, and were also more compliant.

TL;DR: In this paper, the flow characteristics of steel fiber reinforced concrete made with aggregates from sintered pulverized fuel ash and natural sand are reported, and four different types of fibres with varying geometry and aspect ratio were studied.

TL;DR: In this paper, the fracture performance of glass fiber reinforced (GRC) materials was investigated using the traditional compact tension specimen geometry developed initially for testing metals and the fracture toughness results were obtained from the load at the limit of proportionality using linear elastic fracture mechanics.

TL;DR: In this article, the authors describe the properties of mesh reinforced faces of the concrete sandwich beams and the tests used to determine values of modulus and ultimate strength of the reinforced faces.

TL;DR: In this article, the influence of film-forming polymer microparticles on the freeze-thaw resistance of structural lightweight aggregate concrete is studied, and it is concluded that the filmforming microparticle used increased the freezing temperature of the aggregate concrete as well as normal concrete.

TL;DR: In this article, a general formulation of the problem of sensitivity and stability of fracture in plain reinforced cement composites is presented, and it is shown how such phenomena are subjected to very similar laws of scale.

TL;DR: In this paper, the influence of beam depth and span on the flexural strength of plain and fiber reinforced concrete is reported for a basic concrete matrix reinforced with 1.5% by volume of doubly-indented Duoform steel fibres.

TL;DR: In this paper, a crack instability analysis is presented which allows the maximum load stress intensity factor (kc) to be predicted from a pre-determined correlation between kc and a geometric parameter, phi.

TL;DR: In this article, the authors investigated the influence of the absolute joint length on the failure shear stress in precast concrete buildings, especially if these were designed as demountable structures and showed that with longer joints, the shear stresses at failure decreases in the case of medium to high-strength mortar, whereas no influence was found for a ductile joint material.
