workability of the concrete made with partial replacement of fine aggregate (river sand) with CPWS. (STATE METHOD) Compressive Strength Test Metal moulds measuring 150mmX150mmX150mm were used to cast the concrete cubes. A total of 32 cubes were prepared for the mix ratios of 1:2:4 and
But rubber is found to possess properties that are required for viable replacement of fine aggregate in concrete. Hence we in this project have aimed to study the effectiveness of rubber as substitute for fine aggregate and utilize the crumb rubber tyres in concrete, to minimize global warming.
Partial Replacement of Coarse aggregate by Crushed Tiles and Fine aggregate by Granite Powder to improve the Concrete Properties N.Naveen Prasad1, P.Hanitha2, N.C.Anil3 1(P.G Scholar, Department of Civil Engineering, Sankentika Institute of Technology and Management, Visakhapatnam, A.P.
partial or full replacement of fine aggregates. Fine aggregate was replaced with CCB by weight up to 100 % at intervals of 10%. The properties investigated were: workability, density and the compressive strength. The slump test and the compacting factor test were used to assess the workability of the concrete sample specimens.
actual study of evaluating the quality of concrete produced using PWM as partial replacement of fine aggregate in concrete production. Materials: The materials used in this research include cement, water, fine aggregate, polymer, coarse aggregate. Cement: The cement used is ordinary Portland cement manufactured by Dangote Cement Company Plc and
Durability Studies on Concrete with Manufacturing Sand As A Partial Replacement of Fine Aggregate… 46 Table 2 Chemical composition of Manufactured Sand: As manufactured sand is a product from the coarse aggregate industry it will have the same chemical properties of coarse aggregate Constituent Manufactured sand (%) Natural sand Test method
Studies on Quarry Dust as Partial Replacement of Fine Aggregates in Concrete - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Natural sand is most commonly used fine aggregates in the production of concrete possess the problem of acute shortage in many areas.
This present study examines the possible reuse of waste glass crushed into fine and coarse aggregate sizes as partial substitute for natural fine and coarse aggregate in concrete. The variables in this study is both the fine and coarse aggregate while the cement and water-cement ratio were held constant.
The crushed waste ceramic tiles were substituted in place of fine aggregates in the following percentages (0%, 20%, 25%, 30% 35% and 40%) in the concrete mix. The water /cement ratio used was 0.6. The compressive strength of the concrete cast with the above partial replacement of fine aggregate were determined after, 7 and 28 days age of curing.
enable them to be used as partial replacement materials for sand in concrete. Key Words: Quarry Dust, Fly ash, Workability, Compressive strength. I. INTRODUCTION Concrete is the most popular building material in the world. However, the production of cement has diminished the limestone reserves in the world and requires a great
the world. Production of constituents of concrete leads to the depletion of the natural resources as well as it leads to the environmental pollution. Brick-Kiln-Ash is considered as a waste material in the Brick industries. In this study, Brick-Kiln-Ash is used for the partial replacement of Fine aggregate. Fine aggregate is
aggregate replacement material in concrete production such as oil palm shell , periwinkle shell , recycled coarse aggregate  and others. However, to the best of author's knowledge no work has been reported on the use of cockle shells as partial coarse aggregate replacement in concrete .
1. Palm kernel shell serve as a partial replacement of coarse aggregates up to 10% for trafficked roads and 5% for light trafficked roads. 2. For the very lightly trafficked roads in the rural communities' palm kernel shells can be used ass full replacement for the coarse aggregates. This will
Natural fine aggregates (river sand) are replaced by the recycled fine aggregates by the different percentage levels for the production of fresh concrete. A comparative interpretation on the strength characteristics of the concrete produced with Ordinary Portland Cement and Portland Pozzolana Cement is also presented and discussed in this paper.
Studies also focused on used of waste glass as aggregate in concrete production (Rashed, 2014, Taha and Nounu, 2009). Study on durability of concrete with waste glass pointed better performance against chloride permeability in long term but there is concern about alkali-silica reaction.
this thesis, the issues of economic and environmental concern are addressed by the use of waste glass as partial replacement of fine aggregates in concrete. Fine aggregates were replaced by waste glass powder as 5%, 10%, 15% and 20% by weight for M-25 mix.
that using sawdust as partial replacement of fine aggregate up to 25% will contributes to reduction in sawdust waste generation without adversely affecting concrete strength . Close relations were predicted by using groundnut shells for partial replacement of fine aggregate in concrete .
the fine aggregates, CCB and the coarse aggregates. All the investigations were conducted using relevant standards. 2.2.2 Main Investigations Workability Test Workability properties of the concrete with CCB as partial or full replacement of fine aggregates were assessed through the slump test and the compacting factor tests.

BEHAVIOR OF PARTIAL REPLACEMENT OF FINE AGGREGATE WITH CRUMB RUBBER CONCRETE Nithiya P1* and Portchejian G 1 Concrete is one of the most widely used construction materials in the world. Cement and aggregate, which are the most important constituents used in concrete production, are then vital materials needed for the construction industry.
