Silica fume is used to increase strength and durability of concrete, but generally requires the use of superplasticizers for workability. High reactivity Metakaolin (): Metakaolin produces concrete with strength and durability similar to concrete made with silica fume. While silica fume is usually dark gray or black in color, high-reactivity ...
A sand durability test, based on the Micro Deval test method, has been found to be effective in selecting both natural and manufactured sands to provide good skid and skid after wear for the micro texture of concrete pavement whereas abrasion resistance of concrete .
Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material.
On the basis of strength and durability evaluations, it was concluded that both nonair and air-entrained concrete mixtures developed in this investigation are appropriate for manufacture of high-quality, high-durability architectural precast concrete using used foundry sand and fly ash.
Good mechanical properties were obtained for concrete using crushed limestone sand as fine aggregates with a superplasticizer. However, a higher than normally used dosage of superplasticizer is required in these concrete mixtures and the optimum dosage of the superplasticizer needs to be determined for each cement and sand content.

Introduction to Concrete ConcreteSs versatility, durability, sustainability, and economy have made it the worldSs most widely used construction material. About four tons of concrete are produced per person per year worldwide and about 1.7 tons per person in the United States. The term concrete refers to a mixture of aggregates, usually sand ...
The reuse of FS as a substitute for natural sand in concrete production was evaluated based on the mechanical and durability properties of the resulting concrete. Based on the extensive tests carried out on the six mixtures, the following conclusion has been made.
The present investigation is an attempt to study durability properties of concrete with manufactured sand as complete replacement to natural sand and varying percentage of basalt fibers ranging ...
As natural river sand mining is limited by the seasons and a national mining limitation policy has already been issued in China,there is a serious shortage of river sand,which is the main raw material of concrete.Manufactured sands from limestone,granite,basalt etc.have become the green and economical substitute for river sands used in high ...
Effect of granite dust on mechanical and some durability ... The mechanical and some durability properties of these concretes were studied. The results showed an improvement in the workability of the manufactured sand concrete by introducing granite dust.
availability and use of river sand less attractive, a substitute or replacement product for concrete industry needs to be found. River sand is most commonly used fine aggregate in the production of concrete poses the problem of acute shortage in many areas.

comparison of the effects of natural and manufactured sand exert on strength and durability properties. This paper presents the mechanical behavior of the selected fine aggregate, followed by the durability behavior of conventional and M-sand concrete. …
This report describes the effects of various manufactured sands on the durability of concrete, including the effects of w/c ratio and supplementary cementitious materials. A limited investigation was also conducted on the effects of overall aggregate grading and manufactured sand gradation. 17. Key Words Natural sand, manufactured sand, compressive
The effect of quarry dust on the flexural strength of concrete has been experimentally studied and reported in this paper. Concrete used was prepared by replacing 25% and of sand by weight ...
The manufactured sand was made from pre-washed crushed limestone, however, not all the fines were removed by washing and the residual fines content after washing was 3.0%. Table 2 presents a summary of properties of the manufactured sand.
This decrease in batch quantity of sand will reduce the yield of concrete per bag of cement.( yield is defined as the volume of concrete produced per bag of cement) . As an example consider the following case. Mix proportion of 1: 4 by volume with water cement ratio 0.55 is used . Initially there is no bulking of sand since sand is dry.
It is easy to overlook the use of concrete in society. Concrete plays a vital part in our daily lives and in a functioning society. Its benefits to society are immense, being used to build our schools, hospitals, apartment blocks, bridges, tunnels, dams, sewerage systems, pavements, runways, roads and more.
