The optimum replacement of sand with granite quarry dust as fine aggregates should be 15% of the sand fraction in hollow building concrete blocks of the size and mix ratio adopted herein (Osuji and Egbon, 2015). According to Anzar, (2015) the compressive strength of quarry dust concrete continues to increase with age for all the percentage of ...
powder replaced in cement partially, quarry dust replaced in fine aggregate partially and coconut shell replaced in coarse aggregate partially that makes the strength of the concrete maximum. 4) To determine the reduction in cost with efficient partial replacement of these waste marble dust powder, quarry dust and coconut shell.
Nov 24, 2015· The value of strength for 28 th days higher than the strength for 7 th days. 4. Mix ratio of 1:1:2 (cement: aggregate : sand+ quarry dust) gives better strength as compared to mix ratio of 1::3 and can be declared as optimum mix ratio of compressed concrete using quarry dust.
resistance in addition to overall properties of concrete. The optimum percentage addition of the organic inhibitors by weight of cement in concrete containing quarry dust as fine aggregate was also determined Key words: concrete, quarry dust, super plasticizer, corrosion resistance, inhibitor 1. ... To attain strength of 20 N/mm2 a mix
Two control mixes, namely, 1 : 3 cement sand mortar mix, QC series, with 0, 20, 50, and 100 percent partial replacement by weight of natural sand with quarry dust and 1 : 3 cement sand mortar mix with 20% partial replacement by weight of natural sand with quarry dust which was further modified by replacing 0%, 15%, 20%, 25%, and 30% cement with low calcium fly ash by weight (QF series) were prepared.

Kavitha2, Ekneligoda3 and Dolage 1,2,3,4 Department of civil Engineering, The Open University Sri Lanka INTRODUCTION River sand is the most widely used fine aggregate in civil engineering constructions in Sri
Select one sample and thoroughly mix with sufficient water to dampen it to approximately three percentage points below optimum moisture content. Note: If desired, an additional three samples may be mixed at this time with approximate moisture contents of .
An online on site concrete calculator to calculate the concrete mix ratio. It plays a major role in creating a strong, durable concrete block. The major materials needed in the preparation of concrete blocks are portland cement, sand, aggregate (stone), and water.
Dec 21, 2011· Starting at the quarry. Good concrete depends on good aggregate. Coarse aggregate can be as much as 75% of the volume in a mix. The best stone for making concrete is hard, durable particles with moderate absorption. The worst aggregate used to make concrete is friable, weakly cemented sandstones with high absorption.

Aug 10, 2015· Increasing speed has its tradeoffs. Greater speed may decrease depth of bed, but also increases the Gforce, which decreases bearing life. Using the proper opening size for the desired particle separation, along with increased speed, will leave a .
characteristics of concrete with waste marble powder as cementitious material. It was observed that workability of M20, M30 and M40 grade concrete increased with increase in replacement of cement with waste marble powder up to 20%. It was observed that optimum replacement level of marble powder with cement ranges from 10% to 15%.
rials to replace sand and one of the major materials is quarry stone dust. Using different proportion of these quarry dust along with sand, the required concrete mix can be obtained. This paper presents a review of the different alternatives to natural sand in preparation of mortar and concrete.
