2.1 Using Waste Glass Powder in Concrete Mix Basically waste glass powders are made from the waste glass material that cannot be reused due to the high cost of manufacturing. Therefore the manufacture will disposed in the waste landfill. Due to environmental problem, researcher tries to use the waste glass in to concrete, to create a new ...
sustainability Article Evaluation of Physical and Chemical Properties of South African Waste Foundry Sand (WFS) for Concrete Use Patrick Iloh 1,*, George Fanourakis 1 and Aurobindo Ogra 2,* 1 Department of Civil Engineering Technology, School of Civil Engineering and the Built Environment, Faculty of Engineering and the Built Environment, University of Johannesburg, P.O. Box 524, â€¦
The foundry industry in South Africa forms one of the greatest industries in the manufacturing sector. It produces waste foundry sand (WFS) that ends up in landfill sites. Around 80% of the WFS could be utilized as a substitute for sand in concrete. The utilization of WFS will benefit the industry, as raw materials (natural sand alternative) and energy are conserved, while costs of disposal ...
Glass is unstable in the alkaline environment of concrete and could cause deleterious alkali-silica reaction problems. This property has been used to advantage by grinding it into a fine glass powder (GLP) for incorporation into concrete as a
the largest quantities produced in the world. Reusing waste glass in the production of concrete will convert a waste or a burden to a source. If we recycle the glass and use it, it will again become a waste after serving its purpose for a relatively short period of time. Rather if we use waste glass in concrete, it provides a long term solution.
20% of cement was saved. Chemical properties of concrete like sulfate attack re-sistance and alkali aggregate resistance were increased while using these mate-rials. By using these waste materials in concrete, the problems in disposal of these materials on lands get reduced and the environmental pollution is pre-vented. 3. Research Approach
Jun 01, 2017· Utilization of waste glass in ceramic and brick manufacturing process is discussed in a recent study (Andreola et al., 2016). The properties influence the pozzolanic behavior of waste glass and most pozzolans in concrete, are fineness, chemical composition, and the pore solution present for reaction (Imbabi et al., 2012, Rashad, 2015).
Fibrous concrete permits the use of thinner flat and curved structural elements. Steel fibrous shortcrete is used in the construction ofhemispherical domes using the inflated membrane process. Glass fiber reinforced cement or concrete (GFRC), made by the spray-upprocess, have been used to construct wall panels. Steel and
Waste glass is one materials when ground to a very fine powder shows pozzolanic properties which can be used as a partial replacement for cement in concrete. In this paper, an attempt has been made to find out the strength of concrete containing waste glass powder as a partial replacement of cement for concrete.
"The sheet glass cutting industries producing waste glass material, which are not recycled at present and usually delivered to landfills for disposal. Using glass powder in concrete is an interesting possibility for economy on waste disposal
Mechanical and physical-chemical properties of concrete produced ... One of the researchers use glass waste as a 100% substitute for the aggregate and use the metakaolin as a substitute for the ...
Properties of concrete incorporating waste glass as partial substitution for FA amounts of 15%, 30% and 45% were investigated. The waste glass material used was obtained waste collectors. The results obtained show clearly that glass enhances the compressive strength properties of the final concrete product. The study
Developments in chemical admixtures: superplasticizers, air entraining agents, etc., help in controlling production techniques and, in achieving the desired properties in concrete. Use of waste products is not only a partial solution to environmental and ecological problems; it significantly improves the microstructure, and consequently the ...
The fresh and hardened properties of waste virgin plastic mix concrete have been studied (CUR Report 1991). A number of concrete mixes were prepared in which sand was partially replaced by waste plastic flakes in varying percentages by volume. Waste plastic mix concrete with and without superplasticizer was tested at room temperature. Forty-eight cube samples were moulded for compressive ...
Silicones are key to construction and renovation of commercial and residential buildings â€“ from enabling glass walled skyscrapers to enabling energy efficient architecture. At home, silicone sealants and caulks are used to reduce energy usage and prevent damage from moisture and bacteria build-up.
Properties. Sodium silicates are crystalline solids that have a glassy appearance. The common terms for an aqueous solution of sodium silicate are water glass and liquid glass. They produce alkaline solutions, since they are soluble in water. This chemical compound is soluble is â€¦
May 09, 2018· Typical chemical composition contains calcium oxide 40%, silica 35%, alumina 13% and magnesia 8%. The glass content of slagâ€™s suitable for blending with Portland cement typically varies between 90-100% and depends on the cooling methods and the temperature at which cooling is initiated.
For ornamental work, glass is available in wide ranges of texture, colours, finishes and shapes. Traditionally and logically windows are the great â€˜canvasâ€™ of glass art. With the use of glass, architects maintain a deliberate balance between coloured light and airy space. For restoration and renovation, glass craftsman plays an important role.
A major concern regarding the use of glass in concrete is the chemical reaction that takes place between the silca â€“ rich glass particle and the alkali in pore solution of concrete, which is called Alkali â€“ Silicate reaction can be very detrimental to the stability of concrete, unless appropriate precautions are taken to minimize its effects.
