Sir, plz give the detailed specification if we go for design mix with available aggregates and sand by samll mixers at site, if we follows all the instruction given for design mix e;g, water 1.cement ratio 2. grading of aggregates and sand prticlles,2. proper batching and mixing, 3. proper placing with applying vibrator and many other precautions norms of quality control

While M20 grade concrete is used for RCC works (for mild exposure) such as the construction of slabs, beams, columns, footings, etc. 2. Standard Grade: M25, M30, M35, M40, M45, fall in the category of the standard grade of concrete. The concrete grades ranging from M25 to M35 are mostly used to construct RCC works such as footings, columns ...

Answer (1 of 2): Up to M25, Concrete are standard mix the ratio can be stated with out any mix design, From M30 Grade, Concrete will come under design mix. The mix design is need to be calculated according to the specification of the available materials.

Answer (1 of 5): Let we calculate. Example: 1 bag of cement = .035 cum total bag of cement = 0.385/.035 = 11 bags 1 bag of cement = 50 kg of cement 11 bags = 50 x 11 = 550 kg of cement cement required for 1 cum of m25 grade concrete is 550 kg. You can also buy and sell construction materials o...

What is the ratio of concrete in M30 grade? Normally you would find at various places that ratio of various constituents in M30 is 1:1:1. But ideally for all the mix of M25 and above proportion should be determined after doing design mix.if we take case of …

The mix proportions for grades M30 and M60 were obtained using IS: 10262-2009 method of mix design. The obtained mix proportion for M30 concrete was 1:2.20:2.96 with a w/c ratio of 0.40 and 1:1.73:2.46 with a w/c ratio 0.30 for M60 concrete along with superplasticizer [Master Glenium Ace 30(IT)]. Steel fibre content was varied from 0% to 1.5%.

The concrete mix design adopted throughout this study was in accordance with procedure specified in BIS:10262, (), also refer ACI:211 (), and ACI:301-89 to achieve design compressive strength of 20, 25, and 30 N/mm 2, and the mixes are designated as M20, M25, and M30, respectively.Each mix was investigated for three different water cement (w/c) ratios.

How does the Concrete mixing plant works. Concrete mixing plant is divided into four parts: gravel feed, powder (cement, fly ash, bulking agents, etc.) to feed, water and feed additives, transmission and storage stirred their workflow shown in Figure 1., the mixer control system power, into the human – machine dialogue operation interface, system initialization process, …

This mix proportion is designed to obtain economical and specified properties of concrete. It includes M30, M35, M40, M50, M55, M60 & M80. Mix proportions for above grade is find out by following Indian Standard IS-10262-2009 specifications. Classification of grades and their uses. On the basis of compressive strength of concrete, grades of ...

Maximum water cement ratio (As per contract) = 0.45 Mix Calculation: – 1. Target Mean Strength = 50 + ( 5 X 1.65 ) = 58.25 Mpa. 2. Selection of water cement ratio:-Assume water cement ratio = 0.35. 3. Calculation of water: – Approximate water content for 20mm max. Size of aggregate = 180 kg /m 3 (As per Table No. 5, IS : 10262 ). As ...

Next. 1; 2; 3; Home Page; Concrete Batching Plants, Concrete Mixers and other Concrete Production …

Concrete mix design is a design procedure to ascertain the quantities of cement, sand, aggregate, water and admixtures for obtaining a concrete of a required strength like M10, M20, M30, M40, M50 etc., with desired qualities like workability, setting time, etc.,

Now the following steps are displace in the design of M30 grade concrete. Step 1.Calculation of appropriate amount of water for proper hydration of cement: Ultimate ratio of water and cement was taken 0.40. As per Indian Standard Code Specification for 20 mm aggregate water required is 186 liters for the slump

There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent. "M" stands for "mix". Mix represents concrete with designated proportions of cement, sand and aggregate. And the number following "M" represents compressive ...

Concrete Mix design as per IS (Indian Standard) Method. admin March 14, 2021 146 Views 0. Save Saved ... Use Table-1 for finding out water-cement ratio of Plain Concrete and use Table-2 for finding out water-cement ratio of Reinforced Concrete. Table -1: ... M30: 4: Very Severe: 340: 0.45: M35: 5: Extreme: 360:

M30 concrete grade (water-cement ratio of 0.4) is designed as per Indian specifications with discarded tyre rubber as a partial replacement of fine aggregate and quartz sandstone as a partial replacement for coarse aggregates. The water absorption properties of concrete containing crumb rubber, quartz sandstone and a mixture of both were studied.

The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55 and C60. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G ...
