Sand (primarily silica) is used in construction as a component in various materials like concrete, mortar etc. Definitely the salts adsorbed (dissolution might not actually occur) on sand are going to affect the durability in reinforced concrete structures but in plain concrete or mortar for plaster, it might not be that detrimental. It is not that hard to get rid of salts adhered to sand ...
Concrete can withstand these effects when properly designed. The Specifier's Guide for Durable Concrete, EB221 and Design and Control of Concrete Mixtures, EB001.15 are intended to provide sufficient information to allow the practitioner to select materials and mix design parameters to achieve durable concrete in a variety of environments.
for concrete. Ilangovan et al., 2006: studies the strength and behavior of concrete by using crushed rock dust as fine aggregate, they investigated the possibility of using crushed rock as 100 % replacement for sand, with varying compacting factors. Nagraj, 2000: studied the proportioning concrete mixes with rock dust as fine aggregate.

• To observe the variation of durability of concrete upon addition of marble and granite powder. LITERATURE REVIEW • The author of [Bahar Demire,2010] proposed as in this experimental study, the effects of using waste marble dust (WMD) as a fine material on the mechanical properties of the concrete have been investigated.
The Macro Synthetic Fibre Concrete Reinforcement Association (MSFA) is committed to the development of international standards and guidelines for the use of macro synthetic fibre concrete reinforcement. The MSFA is the leading authority on the safe use and development of macro synthetic fibre concrete reinforcement in international markets.
in the production of concrete and cement-sand mortar • The Construction Industry Council has launched a research project entitled "Research on River Sand Substitutes for Concrete Production and Cement Sand Mortar Production". • To identify alternative materials to supplement river sand, the research will go through two phases

The study on the properties of concrete by replacement of natural sand with artificial sand was conducted by Vinayak, 2012. The results have shown that the natural sand can be replaced with the artificial sand up to a maximum replacement level of 60% in order to produce concrete of satisfactory workability and compressive strength.
Jul 14, 2016· If you want to try this on your own kitchen counters, use a small handheld vacuum to pick up the concrete dust as you sand it, recommends Libbie. She lightly smoothed the surface with sandpaper in between each coat of FeatherFinish (heads up: she says it gets very messy). Libbie cautions that patience is a must for this DIY project.
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.
concrete. An attempt had been made in the present investigation to discuss the properties of concrete such as workability and compressive strength of concrete which is prepared by replacing natural sand with artificial sand at different replacement levels (0%, 20%, 40%, 60%, 80% and ). The results have predicted that replacement of
The study investigates the use of crushed rock sand as viable alternative to Natural River sand that is being conventionally used as fine aggregate in cement concrete. Various mix designs were developed for different grades of concrete based on IS, ACI and British codes using Natural River sand and crushed rock sand.
The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.
Durability properties of concrete in which manufactured sand (M-sand) is used as a partial and full replacement for natural sand. To retain the natural resource such as natural sand an attempt is made in this research by partially replacing the natural sand with M-sand. To study basic durability characteristics of concrete M60 grade were selected.
Jan 29, 2014· Cement is simply one of the ingredients of concrete, which is also made of sand and bits of gravel or crushed stone. Cements makes up between 10% to 15% of concrete's total mass; though of course the exact proportions may vary from one mixture to the next, depending on the type of concrete is being made.
