Replacement of Cement in Concrete P. Vipul Naidu1 and Pawan Kumar Pandey2 1Civil-SOT, volume from table for the concrete using crushed coarse aggregates. Adjust the values of water content and percentage of sand as provided in the table for any difference in workability, water cement ratio, grading of.
Concrete mixed with varying substitutions of crushed stone sand as a partial and complete replacement for sand. Several concrete samples were prepared with 0 , 10 , 20 and 100 replacement levels of crushed stone sand substituted for fine aggregate. All these.
Jan 25, 2017 Abstract. Nowadays it is very important to make the concrete economical. Therefore the present work has initiated to make the concrete economical by replacing the natural sand by crushed sand in the concrete. From our study it is concluded that different Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at.

The use of sludge as a substitute for sand or recycled concrete aggregate as a replacement of natural aggregate affected the absorption of concrete. It is impossible to determine the correlation of absorbability and aggregate replacement level. The use of sludge as a sand replacement has increased the permeability of concrete to the greatest.
Replacement of crushed stone waste. Up to 50 of replacement of sand CSW, Concrete is workable for each grade of concrete. 6. B. Basavaraj1, Ravichandra Honnalli2, Sagar N S3, Praveen Ashok M4, Shwetha K C5 (2017). conducted study about replacement of sand with stone crushed powder in conventional concrete stone crusher powder has the similar.
The use of crushed rock sand as a partial replacement of river sand in concrete production was investigated. Water cement ratio varied between 0.55 and 0.59 for 0 to 100 natural sand replacement. The slump ranged between 49 and 60 mm for 0 to 100 natural sand replacement.
Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at 40 to 60 replacement of crushed sand the maximum compressive strength is obtained. The maximum tensile strength of concrete is obtain at 60 and 70 replacement of natural sand with.
Of concrete for grade of M25 with crushed pebbles as fine aggregate were found to be comparable with the concrete made with river bed sand. Crushed pebbles cannot effectively be used in plain concrete in place of fine aggregate. We can use crushed pebbles partially for.
Nov 04, 2013 Findings. The results showed a reduction in compressive strength when 50 per cent of sea shells were used as an aggregate replacement, for both sand and gravel, compared to the control sample. Crushed and graded sea shells used in concrete displayed a lower porosity permeability than.
Apr 10, 2020 The results show that recycled crushed glass can be used to replace up to 60 sand in concrete. However, with an increase in replacement rate, workability of concrete can reduce, and measures need to be taken to improve the workability of concrete by the addition of suitable admixture.
Materials to replace sand. This study aimed to investigate the suitability of using crushed brick in concrete. Crushed brick originated from demolished masonry was crushed in the laboratory and added partial sand replacement. Three replacement levels, 15 ,20 and 25 , were compared with the.

Hameed and Sekar5 (2009) studied the effect of crushed stone dust as fine dust and found that flexural strength increases than the concrete with natural sand but the values decreases as the percentage of crusher dust increases The choice of quarry dust as replacement for sand has been supported in the previous study (Manassa, 2010) showing that.
The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60 to 75 concrete volume (70 to 85 by mass) and strongly influence the concrete’s fresh and hardened properties. Now a day’s sand is becoming a very scarce material. Natural sand deposits are being depleted and causing serious threats to.
