The use of recycled aggregate to reduce the over-exploitation raw aggregates is necessary. This study analysed and categorised properties water-washed, fine coarse, following European Normalization (EN) specification. Because their adequate properties, zero impurities chemical soluble salts, plain concrete was produced using 100% aggregates. Two experimental phases were conducted. Firstly, a la...

Introduction: Amoeboid Olivine Aggregates (AOAs) are irregular-shaped, fine-grained aggregates of olivine and refractory minerals and are important components of C chondrites. The AOAs in CV chondrites have been interpreted to be primary nebular condensates [1] and therefore, can provide constraints on models for nebular condensation. AOAs are intermediate in composition, and may be a link, bet...

Recycled concrete aggregates (RCAs) have been demonstrated as an alternative source to exhaustible natural aggregates. In this paper, we focus on the enhancement treatments for coarse and fine RCAs effect of these durability recycled (RC) made from treated by weakening strengthening cement paste adhered their surface. We conducted comparative analyses improvement mechanical properties. The resu...

The purpose of this study is to identify the differences in porosity and permeability coefficients when mixing ratio aggregates different present satisfying strength requirement compressive specified a specification Korea. Three mix ratios were suggested by considering various aggregate sizes three cylinders made for each ratio. porosities those evaluated through compression water test, measuri...

The micro-texture of fine and coarse aggregates used on roads is one the main factors responsible for skid resistance asphalt pavements. However, long-term behavior this property regarding effects traffic climate conditions has been poorly studied. Therefore, in paper, two types aggregates, schist amphibolite, commonly that are subjected to winter maintenance actions high temperatures summer ha...

A comprehensive suite of geotechnical laboratory tests was undertaken on samples of recycled crushed glass produced in Victoria, Australia. Three types of recycled glass sources were tested being coarse, medium and fine sized glass. Laboratory testing results indicated that medium and fine sized recycled glass sources exhibit geotechnical behavior similar to natural aggregates. Coarse recycled ...
