QUARRY DUST FINE POWDER AS SUBSTITUTE FOR ORDINARY PORTLAND ... Quarry Dust Fine Powder as Substitute for Ordinary Portland Cement in Concrete Mix 193 Journal of Engineering Science and Technology April 2014, Vol. 9(2) enhances compressive strength at hardened state .
Ordinary Portland Cement -Constituents, Properties, Types and ... CachedConstituents of Ordinary Portland Cement. The principal materials used in the manufacture of Ordinary Portland Cement are: Argillaceous or silicates of alumina in the form of clays and shales. Calcareous or calcium carbonate, in the form of limestone, chalk and marl which is a mixture of clay and calcium carbonate. Author: Fasi Ur RahmanSTRENGTH AND DURABILITY STUDIES ON CONCRETE USING QUARRY DUST ... and flexural strengths besides durability of concrete made with Quarry Dust have been investigated. Cement Concrete mix using Quarry Dust as Fine Aggregate is designed using M20. Combinations used for this study, i. Concrete using 100% natural sand as fine aggregate. ii. Concrete using 75% natural sand and 25% Quarry Dust. iii.
Use of Quarry Dust to Replace Sand in Concrete – An ... as quarry dust. The quarry dust is used to sprinkle over the newly laid bituminous road as filler between the bitumen and coarse aggregate and manufacturing of hollow blocks. Various physical properties of the concrete materials are tabulated in Table 1. Table 1: Properties of the materials Material Properties
Characteristic studies on the mechanical properties of quarry ... present study, the hardened and durable properties of concrete using quarry dust were investigated. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the complete replacement for natural river sand. This paper reports the experimental study which Author: A. Sivakumar, M PrakashCited by: 11Publish Year: 2011Study on Compressive Strength of Quarry Dust as Fine ... CachedThe specimens were casted with conventional materials; that is, fine aggregate is natural river sand with M30 grade by using ordinary Portland cement (OPC). With the increase in age of concrete, the compressive strength increases up to 30 percent replacement of quarry dust as a fine aggregate. Author: K. Shyam Prakash, Ch. Hanumantha RaoCited by: 6Publish Year: 2016Water Absorption and Compressive Strength of Self-Compacting ... The material used in this study were Ordinary Portland Cement, water, sand, gravel, quarry dust, fly ash and super plasticizer. The fly ash was a class F fly ash and was obtained from Jimah Power Plant, Tanjong Sepat, and Selangor, Malaysia. Quarry dust was obtained from Negeri Roadstone, Nilai, Negeri Sembilan, Malaysia.
Strength and Durability Properties of Granite Powder Concrete CachedCement The materials of cement was used in an ordinary Portland cement super grade IS: 1489 (53grade) is used. This cement is most commonly used in concrete construction. 2.1.2.
(PDF) Stone Dust in Concrete: Effect on Compressive Strength Experimental programme was conducted using 30%, 40%, 50%, 60% and 70% partial replacement of fine aggregate with stone dust has been taken for concrete of M25 grade with 0.46 water cement ratio.
Cement Hazards and Controls Health Risks and Precautions in ... CachedMix dry cement in well-ventilated areas. Make sure to work upwind from dust sources. Where possible, use ready-mixed concrete instead of mixing on site. When kneeling on fresh concrete, use a dry board or waterproof kneepads to protect knees from water that can soak through fabric.
