1. Introduction. Research on the use of EndofLife Tyre (EoLT) materials in concrete began in the early 1990s. The first studies on the inclusion of rubber particles in concrete, were published following the development of rubberised asphalt. Nowadays, while the world is shifting towards a circular economy, research,, on rubberised cementitious materials continues, aiming to develop high ...
Table : Compressive strength of M20 concrete in 28 Days due to temperature effect Fine aggregate Sand: Quarry dust Compressive strength (MPa) % of reduction in strength compared with control concrete Normal temperature After heated to 100°C 100:0 90:10 80:20
compressive strength were %, %, %,and % respectively. The results of the study indicate that both the density and compressive strength of concrete decreased as the percentage replacement increased but replacement of sand by sawdust produced a higher percentage reduction in compressive strength than in density.
Development of Mathematical Models for Compressive Strength of Concrete Containing Quarry Dust and Waste Plastic as Sand Replacement
Use of Quarry Fine as Partial Replacement of Concrete. The use of quarry dust in concrete according to Chaturanga et al, [7] is desirable because of the benefits such as useful disposal of a byproduct, reduction of river sand consumption and increase in strength Quarry dust has rough, sharp and angular particles, and. 【service online】
This study determines the effect of Sulphuric acid on the compressive strength of concrete with Quarry Dust as partial replacement of fine aggregate at 0 %, 15 %, 25 % and 35 %. A total of seventytwo (72) 100 mm cubes were cast and cured in water up to 28 days. The Compressive strength test was done on the first 36 cubes at 7, 14 and 28 days, while the remaining 36 cubes were exposed to 5 .
The results showed that river sand concrete had greater density and compressive strength than quarry dust concrete for all curing ages. At 28 days of curing, river sand concrete exceeded the target compressive strength by 36%, whereas quarry dust concrete was less than the target compressive strength by 12%.
strength and durability properties of concrete . 23/5/2020· Use of Quarry rock dust as a fine aggregate in concrete draws serious attention of researchers and investigators. This paper presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete.
It is observed that the compressive strength of concrete made using 10% recycled aggregate and 60% stone dust as replacement of coarse aggregate and fine aggregate respectively, is about 11% more ...
High Strength Concrete Using Quarry Dust Replacement Of River Sand. We are a highend mining machinery manufacturer in Asia. The main production equipment includes crusher, sand making machine, ball mill, Raymond mill, cement equipment and other products.
It is found that the compressive, flexural strength and Durability Studies of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete. KEYWORDS River sand Substitute Quarry Rock DustConcrete mixes Compressive Strength Flexural Strengthgain in strength .
The concrete mixturesareshowninTable1 Aftermixing,the initialslump, the concrete specimens (15×15×15 cm) were casted. Aftercasting for24hours, allconcretespecimens were remolded and cured in water at room temperature. Compressive strength of specimens were tested at the agesof7and28days. In summary, the properties of the ...
Objectives: In the present study, byproduct of stone crushed, quarry dust is replaced as a fine aggregate with 20%, 30%, 40%, 50% /Analysis: The fine aggregate is being replaced with fine aggregate and the compressive strength is determined for the concrete by testing the sample cube. The properties such as the specific gravity, fineness modulus, moisture content etc. .
Jun 02, 2016· Concrete Results. The compressive strength of the slump controlled mixes was predominantly governed by the w/c ratio, as observed in Figure 7. The lowest w/c ratio of for natural sand yielded the highest 28 days compressive strength, closely followed by the limestone, granite, basalt and gritstone sands.
Jul 01, 2017· 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 ...
Jul 31, 2020· Concrete is the most widely used composite material today. The constituents of concrete are coarse aggregate, fine aggregate, binding material and wat.
However, the use of fly ash leads to a reduction in early strength of concrete. The use of quarry dust in concrete is desirable because of benefits such as useful disposal of a byproduct, reduction of river sand consumption, and increased strength. However, the use of quarry dust leads to a reduction in the workability of concrete.
Samples of concrete (eg. cubes) were made using varying contents of laterite and quarry dust as fine aggregate. The quantity of laterite was varied from 0% to against quarry dust at intervals of 25%. The samples were cured for specified periods and tested in the laboratory for compressive strength.
quarry dust is reduced by the addition fly ash. This paper investigates the workability and strength characteristics of Quarry Dust Concrete (QDC) containing 0% to 30% of fly ash. Based on the test results, it can be concluded that combined use of quarry dust and fly ash can be shown improved strength in concrete and also
Use of fly ash in quarry dust mixes is found helpful in reducing the shrinkage of quarry dust concrete. Results indicate that quarry dust can be effectively used to replace sand and fly ash can improve the performance of concrete with quarry dust as fine aggregate.
