Alternative Of Fine Aggregates In Concrete Pdf

ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Fine aggregate are basically sands won from the land or the marine environment.

Jul 28, 2016 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 ...

Aggregates Are Mainly Classified into Two Categories: Fine aggregate; Coarse aggregate; The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately.

FINE AGGREGATE Locally available Mahanadi sand was tested for its suitability as fine aggregate as per IS: 383-1970. Results of the tests are as summarized in Table 2. Table 2: Physical properties of natural sand S. No. Properties values Range as per code IS: 383-1970 1 Specific gravity 2.71 2.30-2.90 2 Bulk density (kg/m3) 1503 1280-1920

Aggregate occupy about 60 – 70% volume of concrete. In this percentage 40 to 50 % proportion of aggregate is fine aggregate (sand). Fine aggregate selection plays vital role in concrete performance and its cost. Lately the need for replacing sand with alternative materials have picked governing serious environmental impact of dredging sand ...

Hence, there is the need to study the feasibility of Dandagala et al;(2014) have made laboratory investigation on green coconut shells and matured coconut fibre as the aggregates coconut shell in concrete, an alternative low cost building material for concrete preparation in the future research programme. and reached at following findings that ...

Recycled Glass Concrete: Coarse and Fine Aggregates

Mar 01, 2018 Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal …

the fines content in fine aggregate for concrete in the draft CS3 could be revised as follows: – Maximum fines content in fine aggregate for use in ordinary concrete: to be reduced from the current value of 16% stipulated in the BS 882 to a lower value of, say, 14%. – Maximum fines content in fine aggregate for use in marine concrete

aggregate. In the laboratory test, conventional fine aggregate was replaced at 100% replacement level. A total of 18 cubes were cast, cured and tested. The strength development of the concrete mixes containing egg shell aggregates was compared to that of conventional concrete with sand as fine aggregate.

non-conventional aggregates such as Ceramic waste and quarry dust were used in concrete to progress the properties of concrete and to reduce cost [3]. Increase in the cube strength to the extent of 3.9% at w/c ratio of 0.46 with replacement of 20% ceramic

The problems is the use of alternative materials for incorporation of both Metakaolin and Silica fume in river sand such as artificial fine aggregate, concrete was found to reduce the free drying industrial by products (some forms of slag, bottom shrinkage and restrained shrinkage cracking width. ash), recycled aggregates, etc.

In this investigation, two types of fine aggregates were used for preparation of concrete, Natural fine Aggregate & Crushed Fine aggregate. (NFA & CFA) Natural Fine Aggregate (River Sand) Natural fine aggregate (NFA) used for this entire investigation for concrete was river sand conforming to zone-I of IS: 383-1970 TABLE VII.

proper utilization of PG as a partial replacement of (a) fine aggregates in cc-pavements (b) cement in cc-pavements. The study includes the material characterization of PG sieve analysis, specific gravity, moisture content, workability, compressive strength, flexural strength, unit weight, normal consistency, and initial and final setting time.

as fine aggregate. The replacement of the rubber tyres aggregates in concrete was done in three phases. In the first phase, fine rubber tyres aggregates were used to replace 50% of the normal sand. Secondly, coarse rubber aggregates tyres were used in the replacement of 50% of the normal gravel.

to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95). There has not been much research on the effects of coarse aggregate content

The use of alternative materials as substitutes for ordinary aggregates, mainly in concrete and mortar, has been common in recent decades in Brazil. Due to its physical and chemical similarities to common aggregates, ceramic waste, when coupled with a granulometric control, is suitable for use as an aggregate in concrete. Brazil has been estimated to dispose of approximately 25,000 tons of ...
