This paper investigates the water permeability, consistency and density of architectural mortar with various contents of glass sand as fine aggregate. To reduce the effect of alkali-silica-reaction (ASR), metakaolin (MK) was used as supplementary cementitious material (SCM) instead of a component of white cement. The microstructure of glass sand mortar was visualized by means Author: Guoqing Jing, Gang Huang, Wenjun Zhu. Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. It normally refers to the duration or life span of trouble-free performance. Different concretes require different degrees of durability depending on the exposure environment and properties desired. The aim of this investigation is to study the use of the water soluble polyethylene glycol as self-curing agent. The function of self-curing agents is to reduce the water evaporation from concrete and hence they increase the water retention capacity of concrete compared to the conventionally cured use of self-curing admixtures is very important from the point of view that Author: S.

Introduction. Cementitious materials, mainly in the form of concrete are the most widely used construction material in the world because of easy availability of its constituent materials and unique properties; every year more than 1 m 3 of concrete is produced per person worldwide.However, the sustainability and durability of reinforced concrete structures are still the main Cited by: 4.
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (for its.

An Investigation into the Use of Manufactured Sand as a % Replacement for Fine Aggregate in Concrete sand concrete exceeds that of natural sand concrete. ANN proved a valuable and reliable method of reference to the effects of clay particles on.
Concrete is resistant to wind and water. Therefore, it is very useful in storm shelters. As a soundproofing material cinder concrete could be used.
Disadvantages of Concrete. Compared to other binding materials, the tensile strength of concrete is relatively low. Concrete is less ductile. The weight of compared is high compared to its strength.
These were mixed in different proportions to get a consistent combined FM. The combined FM is determined like All-in-aggregate FM. In the present study we have selected M30 Grade of concrete mix. To find out the effect of fineness modulus (FM) of sand on concrete, sand of different FM from to is chosen.
