Analytical Study on Influence of Mortar-aggregate Interface Character on Concrete Strength by Rbsm
Concrete is a heterogeneity material consisting of mortar and aggregate in meso scale. Evaluation of fracture process in this scale is useful to clarify the material characteristics of concrete. However, analytical approach in this scale has not been carried out enough yet. And in meso scale, mortar-aggregate interface is the weakest part in concrete so that it is considered that its material p...
متن کاملInfluence of Aggregate Size and Fraction on Shrinkage Induced Micro-cracking of Mortar and Concrete
In this paper, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated. Nonlinear finite element analyses of model concrete and mortar specimens were performed. The aggregate diameter was varied between 2 and 16 mm. Furthermore, a range of volume fractions between 0.1 and 0.5 was studied. The nonlinear anal...
متن کاملInfluence of aggregate size and volume fraction on shrinkage induced micro-cracking of concrete and mortar
In this paper, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated. Nonlinear finite element analyses of model concrete and mortar specimens with regular and random aggregate arrangements were performed. The aggregate diameter was varied between 2 and 16 mm. Furthermore, a range of volume fractions betw...
متن کاملProperties of Cement Mortar by Use of Hot-Melt Polyamides as Substitute for Fine Aggregate
This paper presents an experimental study on use of hot-melt polyamide (HMP) to prepare mortar specimens with improved crack healing and engineering properties. The role of HMP in the crack repairing of cement mortar subjected to several rounds of heat treatment was investigated. Compatibility between HMP and hydraulic cement was investigated through X-ray diffraction (XRD) and Fourier transfor...
متن کاملEffects of Aggregate on Flow Properties of Mortar
The effects of aggregate characteristics on flow ability of mortar mixtures were investigated. Two types, five single sizes, and three gradations of fine aggregate were considered. Uncompacted voids of the aggregates were measured. Flow properties of 166 mortar batches made with the aggregates, together with different sand-to-cement ratios (s/c) and water-to-cement ratios (w/c), were evaluated ...
