Cement substitution in self compacting concrete (SCC) is emphasized to conserve environment, reduce cost and utilize waste materials. This paper focuses on comparing the permeability and drying shrinkage of SCC containing Wollastonite micro fiber (WMF), a cheap pozzolanic fiber with respect to flyash. Microsilica was added for providing required viscosity to maintain homogeneity of the mixes. T...

With many years of construction and application of common concrete, researchers have always been searching for a better composition. One of the notable ideas for achieving such a composition is using recycled materials. One of the materials which is suitable for environment and constant development is damaged tires .For studying mechanical properties of concrete containing tire particles, a ser...

The most common and reliable material without which modern construction is indispensable concrete. development of production pushing for new solutions to improve the quality concrete mix demanded significant indicators a mixture are compressive strength mobility mixture. Every year, volume research on nanomaterials as modifying components significantly increasing, results indicate prospects the...

Nowadays under the conditions of intensively developing construction production, hardening time and strength Portland cement are becoming more relevant research issues this type binder. The basic requirements to stated in normative industry documents considered. limits normal fast-hardening given. Raw materials for production high-strength must be homogeneous provide a high degree fineness bind...

Introduction: The paper addresses the effect of a composite modifying mineral additive based on waste — tailings from Balkhash Mining and Processing Plant microsilica structural characteristics performance heavy concrete. Purpose study: We aimed to select optimal B25 B35 concrete mixes MV-D20 modified binder with in its composition evaluate Methods: In course study, standard methods were used d...

This paper examines the performance of multi-binder conventional geopolymer mixes (GCMs) with relatively high early strength, achieved through curing at ambient temperature. Mixes incorporating ground granulated blast-furnace slag (GGBS), fly ash (FA) and microsilica (MS) sodium metasilicate anhydrous, were assessed in terms workability, mechanical properties embodied carbon. A cement mortar wa...

The paper is aimed at the study of resistance cement pastes containing various secondary materials (fly ash, zeolite, zeoslag, slag and microsilica) in model environment acid rain. Changes characteristics studied due to rain, such as compressive strength composites, water absorption, penetration aggressive ions, pH material its chemical composition were analysed. Model acidic environments repre...
