Ewaste is used as one such alternative for coarse aggregate. Owing to scarcity of coarse aggregate for the preparation of concrete, partial replacement of Ewaste with coarse aggregate was attempted. The work was conducted on M20 grade mix. The replacement of coarse aggregate with Ewaste in the range of 0%, 5%, 10%, 15%, and 20%.
1. Recycled aggregate concrete may be an alternative to the conventional concrete. 2. Water required producing the same workability increases with the increase in the percentage of demolished waste. 3. Up to 30% replacement of coarse aggregate with recycled aggregate concrete was comparable to conventional concrete. 4.
Asbestos sheet waste also a solid waste used as a coarse aggregate in the concrete mixes. Asbestos products manufacturing industries are located in fifteen industrial states of India strategically important from raw materials and energy availability view point and also from consumption pattern view point.
material by checking its suitability for reuse as coarse aggregate replacement in M 20 concrete mix. The optimum eplastic waste content to be added as a partial replacement of coarse aggregate was determined and compressive and split tensile strength of mix with % variation (5,10,15%) of Ewaste with conventional concrete with and without addition of 10% fly ash were compared.
The recycled aggregate (RA) was obtained from a recycling plant (Fig. 1) for demolition waste in the UAE, where the waste concrete is segregated into different categories and crushed into different sizes. Following Dubai municipality specifications, the aggregate used in .
1) To determine the suitability of brick waste as replacement of coarse aggregate in concrete production. 2) To investigate the mechanical and physical properties of brick waste concrete 3) To compare the performance between concrete with brick waste as coarse aggregate partial replacement and conventional concrete (control concrete).
aggregate marginally improves compressive, tensile and flexural strength in concrete. Keywords: WMDWaste Marble Dust, Concrete, Strength, Reuse, Replacement 1. Introduction Concrete is an extensively used building item and consists of cement, coarse aggregate, fine aggregate .
of concrete (M201::3) produced using coconut shell as substitute for conventional coarse aggregate with 0%, 25%, 50%, 100% partial replacement. Three sample cubes are prepared for M20 grade concrete mix for each case another aim of this paper is to spread
are generated as a waste during the process of dressing and polishing. It is estimated that 15 to 30% waste are produced of total raw material used, and although a portion of this waste may be utilized onsite, such as for excavation pit refill, The disposals of these waste materials acquire large
tiles (CT) as a coarse aggregate in the concrete mix. The CT is an industrial waste material, and then reuses it in the construction fields will reduce the concrete costs and reduce the environmental pollution. The general properties, such as the specific gravity, water absorption
Jun 01, 2010· – A current trend is to use waste and by‐products in concrete to replace binders and aggregates. This trend reduces the impact on the environment and the use of finite natural resources. This paper aims to investigate whether concrete which includes crushed, graded and washed recycled construction demolition waste, used as a coarse aggregate, can be manufactured to a comparable .
Halickaet al. [5] used ceramic sanitary ware waste as coarse aggregate in concrete mixes. Thescanning electron microscopy of the ceramic particles revealed the porosity of their structure. Also, by investigating its properties, it was noticed that ceramic aggregates has .
Natural aggregate is the main source of aggregate used in concrete work in Iraq. Synthetic aggregate is also used in limited scale around the world. An industrial solid waste is produced from iron and steel industry. It was physically treated and fully inspected and incorporated in concrete as coarse aggregate. The concrete mixes were made with three mix proportions 1:1:2, 1::3 and 1:2:4.
Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications. According to a 2004 FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate .
STUDIES ON STRENGTH CHARACTERISTICS ON UTILIZATION OF WASTE MATERIALS AS COARSE AGGREGATE IN CONCRETE ... In the mix proportion for concrete using waste aggregates, the conventional stone aggregate was completely replaced by .
The reused of ceramic tiles waste as aggregate in concrete has a positive effect on environment and study deals with reviewing the usage of ceramic waste tiles as coarse aggregate replacement in concrete and its effect on workability, compressive strength, splitting tensile strength and flexural strength of concrete.
The concrete mixture was made in a weight ratio of 1 PPC: 2 Fine Aggregate: 3 Coarse Aggregate, with water cement ratio of Five concrete mixtures were made each by replacing coarse aggregates in concrete mixtures with BSW of 0%, 25%, 50%, 75%, and 100%. A mixture with 0% BSW coarse aggregate was a control concrete.
g) Concrete using Goldmines waste coarse aggregate is resistant to chloride attack after immersion for a period of 28 days h) As per cost analyses, concrete using GMW coarse aggregates is economical than concrete using local coarse aggregates, the more economy can be achieved if it is used nearby Hutti goldmines Raichur.
of thermoplastic waste in concrete, the use of two different thermoplastic polymers, high density polyethylene and polypropylene, has been studied, as a part of the conventional aggregates in concrete pavements with useful results [2, 3]. Generally, the replacement of .
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.

In this project coarse aggregate are partially replaced by electronic waste up to 5%, 10%, 15% and are checked for its compressive strength and prospects of ewaste consumption in rigid pavement are assessed [15]. Objective To find an alternative method for disposal and management of electronic waste in ecofriendly way.
This research focuses on a study of the strength of concrete with ceramic waste as coarse aggregate and quarry dust as fine aggregate. The sources of ceramic waste and quarry dust are obtained from the industrial in Malaysia. Presently, in ceramics industries the production goes as waste, which is not under going the recycle process yet. In this study an attempt has been made to find the ...
