This paper presents the fresh and hardened properties of high-strength concrete comprising byproduct fine crushed aggregates (FCAs) sourced from the crushing of three different types of rocks, namely granophyre, basalt, and granite. The lowest void contents of the combined fine aggregates were observed when 40% to 60% of natural …
Concrete is commonly used building material, and it is extensively used, hence this project is aimed to reduce the use of natural sand by using crushed rock powder(CRP) as a replacement for fine aggregate in …
In this study, fine stone powder (FSP) generated in the process for producing crushed coarse and fine aggregate was used as a partial replacement for the fine aggregate. The durability of mortars was investigated under sulfate attack in terms of compressive strength loss, change in mass, and expansion. Cement mortars were made …
Key words: crushed rock powder (CRP), plastic coarse aggregate (PCA), natural coarse aggregate (NCA), partial replacement. fine aggregate, thereby providing a sustainable option to deal with plastic and quarry waste. II. METHODOLOGY. Materials used: Cement: Ordinary Portland cement (OPC) 53 grade confirming to IS: 8112 was …
Three different quarry dust wastes replaced the river sand aggregate: limestone, marble, and basalt powder as fine filler aggregate in three different replacement ratios of 25%, 50%, and 75% to ...
This paper represents the experimental studies carried out from the use of rice husk as partial replacement for fine aggregate in concrete mix. This fine aggregate was replaced by 0%, 5% and 10% ...
In this study, effects of crushed stone waste from Katunun's quarry as fine aggregate on mortar and concrete properties will be examined. Samples with varying crushed stone waste replacement ratio, ranging between 0% until , will be analysed at 3, 7 and 28 days curing time. Mortar sample is using 0.5 w/c ratio, while concrete …
The experimental result shows that the strength properties of cement concrete incorporating acceptable solid waste consisting of crushed stone dust were homogenous and much higher than conventional concrete. The cement concrete stone dust CCSD 7.5 with partial replacement of 7.5% stone dust shows an increase in compressive and …
The present study is aimed at utilizing Crushed Rock Powder as fine aggregate in cement mortar and cement concrete, replacing natural sand. The study on mortar …
A 15% replacement slightly reduced both strength and durability. (Premalatha & Srinivasan, 2019) analysed concrete properties by replacing river sand with glass powder. Testing various concrete grades with up to 50% glass powder replacement for fine aggregate, they found improvement in strength up to 30% replacement.
The use of such materials not only results in conservation of natural resources but also helps in maintaining good environmental conditions. The present investigation aims in the study of properties of mortar and concrete in which Crushed Rock Powder (CRP) is used as a partial and full replacement for natural sand.
Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and …
In this study, fine stone powder (FSP) generated in the process for producing crushed coarse and fine aggregate was used as a partial replacement for …
To reduce the impact of the quarry dust on environment and humans, this waste can be used to produce a new product by partially replacing fine aggregates with quarry dust in concrete. The main aim focus of this …
Fine granite powder is a nice aggregate that is produced by way of crushing stone, gravel or slag. The combination fabric less than four.75 mm this is processed from beaten rock or gravel and supposed for production use. Fine granite powder is a material of high quality, in contradiction to non-refined surplus from coarse …
The Dust contents higher than 15% increases the water absorption of the. concrete. Partial replacement of sand by stone dust in concrete also reduces workability but the. compressive strength and ...
Abstract. In this study, effects of crushed stone waste from Katunun's quarry as fine aggregate on mortar and concrete properties will be examined. Samples …
Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
The justifiable solution for the production of cement can be the adequate utilization of waste products like crushed stone dust as a partial replacement of …
That's why, rather than the use of sand, it is necessary to find a replacement of natural fine aggregate. Stone dust is a by-product from rock crusher and it can be recycled by using it in the ...
It is found that crushed brick mortar (CB) fine aggregate have more dust and fine particles lesser than 75 μm than crushed concrete aggregates (Martinez et al., 2013; Aggarwal and Siddique, 2014). The fineness modulus of the CB is around 3.60–3.91 whereas for crushed concrete is around 3.10–3.65 ( Martinez et al., 2013 ; Katz and …
Crushed stone sand and crushed gravel sand are examples of natural sand deposited by rivers, crushed stone sand obtained by crushing stones, and crushed gravel sand. In the study, natural river sand free from dust impurities and complying with the ASTM C33 was used. The gradation of the fine aggregate is presented in Fig. 2.
2. Rock Dust Characteristics. Aggregate is defined by the European standard EN 12620 [] as granular materials of natural, manufactured, and recycled origin used in the construction industry.Similar definitions are provided from various ASTM standards [25,26].The aggregate grains are originally part of the parent rock and are …
3.3 Fine aggregates In the present Work crushed stone aggregates was used as fine aggregate and test were conducted as per IS:2386-1997 Part-III and IS:383-1970. Table -3: Properties of the fine aggregate Characteristics Test Results Specific Gravity 2.69 Water Absorption 2% fineness modulus 2.90 Bulk density in loose state Ingredients 1420 kg/m3
Results showed that the two-layer beams with clam-shell aggregate concrete 1:2:3 with a depth of 50mm at the tension layer and 100mm of crushed stone aggregate concrete 1:2:4 mix at the ...
natural agg regate such as gravel or crushed rock, sand & fine p articles of cement powder & ultimately mixed with the water. While th e construction material cos t is increasing day by day;
support for the use of Quarry Rock Dust as fine aggregate in concrete Manufacturing. Thus, it can be conclude that the replacement of natural sand with Quarry Rock Dust, as full replacement in concrete is possible. The reduction in waste generation by manufacturing value added products from the granite stone waste will boost up the
Common river sand is expensive due to excessive cost of transportation from natural sources. Also large-scale depletion of these sources creates environmental problems. As environmental transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product for concrete industry needs to …
Crushed rock sand – An economical and . Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve. Cited by: 15WhatsApp
natural aggregates. So Crushed waste tiles and granite powder are introduced as a replacement for the coarse aggregates and fine aggregates. The waste crushed tiles were used as coarse aggregates' replacement by 10%, 20% and 30% and granite powder were replaced in place of fine aggregate by 10%, 20% and 30% without any change the mix …
