(a) DESIGN STIPULATION:-Target strength = 60Mpa Max size of aggregate used = 12.5 mm Specific gravity of cement = 3.15 Specific gravity of fine aggregate (F.A) = 2.6 Specific gravity of Coarse aggregate (C.A) = 2.64 Dry Rodded Bulk Density of fine

The various strength aspects analyzed are the flexural and compressive strength of the coconut fiber concrete at variable percentages (1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%) by the load of cement of fiber. This research is based on the use of coconut fibers in structural concrete to enhance the mechanical properties of concrete.

Cement production also consumes huge energy and natural resources and causes about 7% of total greenhouse gas emissions in the world. The main objective of this investigation is comparative study on strength between Fly Ash based concrete and Normal Concrete in M20,M30 and M40 grades of concrete.

The M60 grade raft has been designed with thickness ranging from 2 to 3 metres at various locations, thus applying mass concrete requirements of peak temperature and temperature differential.

M60 and M80 Grade Concrete. It is used as Reinforced Cement Concrete. These grades of concrete made for the structures where high strength concrete is usually required. It is used for high rise buildings, bridges, long-span bridges. Both of these perform exceptionally in highly aggressive environments.

The variable factors considered in this study were concrete of grade M60 for a curing period of 28 days, 60 days and 90 days of the concrete specimens in 1%, 3%, 5% H2SO4 and HCl solution.

The constituents of geopolymer concrete of 8, 12 and 14 molarity sodium hydroxide for M20, M30, M40, M50 and M60 grade concrete is shown in Table 1.

Even then the proportions of the materials of the concrete found at the laboratory require modification and readjustments to suit the field calculation. In this design project we have designed M60 grade concrete using Design mix of American Concrete Institute method, and also found out compressive strength for design mix method.

The real water concrete proportion utilized in blend structure for M60 grade concrete is 0.29 for 50 mm to 75 mm droop. The solid shapes and shafts are casted and tried for compressive quality and flexural quality separately at 7 years old days and 28 days.

This document summarizes a project to develop high-performance concrete with a compressive strength of 60 MPa. Through four trials, the researchers determined that a water-cement ratio of 0.27 and superplasticizer dosage of 0.9% was sufficient. To make the design more economical, they conducted one additional trial replacing 11% of the …

The cost of concrete is governed by the cost of material, plant and labour. The cost of cement is several times higher than the aggregate. Therefore, the objective is to produce the concrete mix as lean as possible and should be economical. That is why designed mixes are preferred to nominal mix. Generally in nominal mixes, cement in higher …

Contemporary vogue in concrete expertise was to use Industrial, Agricultural trash as Supplementary cementations materials for the development of blended cement concretes. RHA is one of waste from agricultural industry. In the present Article, Rice

The objective of this research attempt was to prove experimentally the effects on the behavior of concrete under elevated temperatures of different grades (M20, M40 and M60) of concrete.

Rajesh et al. [25] conducted the tests to explore the high strength concrete (HSC) M60 grade concrete properties with Alccofine at 5%, 10%, 15%, and 20% replacement.

The paper presents an experimental procedure for the mix design of self-compacting concrete for grade M60 and implementation of the same mix at cast in situ heavily dense reinforcement structure ...

The workability of M40 and M60 grade concrete with and without replacing Nano TiO2 has been studied by conducting slump cone and compaction factor tests. At last, the characteristic strength of both grades of concrete have been studied by performing accomplish compression test and split tensile test.

Different Grades of Concrete like M1O, M20, M25, and M30 denote concrete models according to their difference in strengths.

Concrete mix design – M70 grade of concrete provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors. Characteristic strength given by the relation 70 + (1.65 *5 ) = 78.25 N/mm 2. 20 Mm = 24, 10 mm = 36, r/sand = 20, c/sand = 20. Aggt: cement = 2.82 : 1.

M5, M10, and M15 grades of concrete are mostly used in Plain Cement Concrete (PCC) works as bed concrete below column footing. While M20 grade concrete is used for RCC works (for mild exposure) such as the construction of slabs, beams, columns, footings, etc.
