Apr 18, 2015· experimental investigations of strength characterstic of geopolymer concrete by using fly ash and quarry dust (without cement)
Suitability of Quarry Dust as Partial Replacement Material for Sand in Concrete ... In the presence of silica fume or fly ash, quarry dust can be a suitable ... the high content fly ash concrete ...
quarry dust and fly ash using the slump flow test and the jring test. Moreover to determine the water absorption and compressive strength performance of selfcompacting concrete incorporating quarry dust at different percentages and fly ash at a fixed percentage. Review
Granite fines or rock dust is a byproduct obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available.
Fly ash can be used as prime material in many cementbased products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement. Road construction projects using PCC can use a great deal of concrete, and substituting fly ash provides significant economic ...
Fly ash and Quarry Dust in a Concrete Indumathy V Department of Civil Engineering, Anna University, Chennai. Abstract This paper presents the results of an experimental investigation carried out to evaluate the compressive strength and transverse strength of 1:3 mortar mixes in which natural sand was replaced with
Yes As quarry dust(also called as crushed sand) is a byproduct obtained after crushing of stones(rocks) to make aggregates. * Results have shown that the concrete ...
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and ...
May 01, 2017· To address the environmental constraints due to cement production and sand scarcity, strength properties of highcalcium fly ash (CFA)based geopolymer concrete with quarry dust as fine aggregate is explored in this paper. River sand was replaced with quarry dust from 0 to by mass.
Hence, partial replacement of cement becomes a necessity as well as natural sand in concrete by waste material or byproduct without compromising the quality of the end product. Partial replacement with Ground Granulated Blast furnace Slag (GGBS), Fly Ash (PFA), Silica Fumes (SILICA) incorporates with of Quarry Dust (QD) as sand replacement.
Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age.
Partial Replacement of Sand by Quarry Dust in Concrete Sumit L. Chauhan, Raju Assistant Professor P. I. G. C. E. Nagpur . Abstract The paper describe the role of quarry dust In the construction of buildings and other structures to eliminate the demand of natural sand by using quarry waste to replace the use of natural sand.
A STUDY OF COMPRESSIVE STRENGTH OF MORTAR . Normally fly ash is used for 1535% by weight of cement and fly ash (5). However when using the quarry dust instead of sand, the compressive strength is increased as same as in the case of without fly ash.
(1)Fly Ash Brick This bricks are manufacturing by mixing Quarry Dust / River Sand, Stone aggregates less than 6mm in Size, Cement and Fly Ash ( Fly Ash quantity will be 10% to 20% of Cement ). Normally the actual cement quantity required will be ...
In series A 15% of cement, 50% of quarry dust and 25% of both of fly ash and billet scale were used. In series B, the ratio of billet scale and fly ash was increased to 40% and cement and quarry dust were decreased to 10% and 50% respectively to have a better understanding on the effect of .
quarry dust and fly ash in order to moderate the cost of mortar. The main objective of this work is to study the compressive strength of mortar cubes by various combinations of cement and fine aggregate replaced by Epoxy resin, fly ash, and quarry dust at the age of 7 days. The results of mortarmade with cement replaced with 20%,
proportion of fly ash and for different age of concrete. From the results obtained it can be clearly seen that for 10% to 20% replacement of fly ash with weight of cement compressive strength is increases and then if we further increases percentage of fly ash, compressive strength decreases.
investigation presents the experimental work of partial replacement of cement by class C fly ash along with quarry dust for sand. The cement is replaced by fly ash at 10%, 20%, 30%, 40% with quarry dust by 0%, 25%, 50% of concrete specimens were prepared. The specimens are curing at the ages of 7, 28, 60 days and tested for compressive and split
This paper reports the experimental study undertaken to investigate the influence of partial replacement of sand with quarry dust, and cement with fly ash on the concrete .
