The well-known key problem with concrete is that its compressive strength and the compression modulus are insufficient for a variety of applications. Our polymer concrete (PC) consists of an unsaturated polyester resin as the polymeric matrix, silica sand as the inorganic aggregate, plus atactic polypropylene (PP) fibers. A further property improvement can be achieved by gamma irradiation and w...

Recycling of asphalt concrete is increasingly used as a major rehabilitation method in Japan because it can conserve natural resources, reduce costs and save energy. In this study, reclaimed asphalt concrete from Tokyo International Airport was evaluated for use in four types of base materials: recycled granular material, recycled cement stabilized material, recycled cement-emulsified asphalt s...

Abstract—Drying is a phenomenon that accompanies the hardening of hydraulic materials. This study is concerned the modelling of drying shrinkage of the hydraulic materials and the prediction of the rate of spontaneous deformations of hydraulic materials during hardening. The model developed takes consideration of the main factors affecting drying shrinkage. There was agreement between drying sh...

The experimental study deals with Hybrid fibre reinforced concrete with the use of (Polypropylene and Recycled polyethylene terephthalate RPET). The M40 grade concrete used was designed by using IS10262-2009 code. The steel fibre and synthetic fibre were added at the volume fractions up to 0.5%. Test results showed that the fibres, when used in a hybrid form, could result in superior composite ...

This work aims to investigate different predictive models for estimating the unconfined compressive strength and maximum peak strain of non-structural recycled concretes made up by ceramic concrete wastes. The extensive experimental campaign carried out during this research includes granulometric analysis, physical chemical compression tests along with use 3D digital image correlation as a meth...

Special libraries all over the world today fulfil a whole variety of different services at a wide range of locations. This diversified spectrum of activities is by no means a recent development. At the time that the Special Library Association (SLA) was founded at the 1909 conference of the American Library Association (ALA), special libraries already had little to do with traditional library t...

One of the most dangerous types cyclic effects, especially inherent in several regions world, is alternating impact wetting and drying on concrete reinforced structures. In current scientific literature practice, there not enough fundamental applied information about resistance to variotropic concretes obtained by centrifugal compaction methods. The purpose study was investigate effect various ...

Recycling end-of-life tires is a global problem that requires an urgent solution. Storing and preserving these challenge delays facing potential problems instead of solving the problem. In this context, recycling waste without harming environment at low costs has been focus many researchers. For several decades, possibility grinding to aggregate size for concrete substituting them with natural ...
