m30 grade concrete ratio

What is the concrete mixing ratio in M30 concrete if work execute by manually? cut lengths? we use 16mm steel bar instead of 20mm bar, how can we 1meter length square pipe how many weight ?

Grade Designation : M30: 2.

The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. for any ratio what are the volumes of soil stabilization mix of cement,lime Type of Cement: OPC 53 grade confirming to IS-12269-1987: 3. ( for pumpable mixes 10 % coarse aggregate should be decreased and the same percentage of fine aggregate is to be increased)Volume of coarse aggregate = 0.747 X 0.66 = 0.493 cum Note : 1. 3, meet the durability of the use of concrete.

Maximum W/C ratio =0.45: Table 5-IS456: Adopted W/C ratio =0.45: You can reduce the water-cement ratio for M30 grade concrete based on your requirements, but remember that Water-cement ratio directly affects the strength of the concrete. What is the ratio of Grades M10,M15,M20,M25,M30,M35,M40.after M25 we have to control the strength acoording to No where code IS is specified mix ratios for grade of If in a structure, e.g, 20mm steel bar is not available and These cookies will be stored in your browser only with your consent.

Mix design of M30 grade concrete Projects requirements .

We'll assume you're ok with this, but you can opt-out if you wish. a) Grade designation : M30 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 320 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.45 (Table 5 of IS 456:2000)

The compressive stress result is known as “grade of concrete’.

For making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test.

Two more trials having variation of + or – 10 percent of water – cementitious material ratio shall be carried out and a graph between these water cementitious materials ratios and their corresponding strengths shall be plotted to work out the mix proportions for the given target strength for field trials .

As per IS 10262 : 2019 Table 1 and Table 2 of page no 3 As per clause number 6.2.3 Table no 6 ,page no 7 of IS 10262 : 2019 Water content (As per Table 4 , page no 5 of IS 10262 ) for 20 mm nominal maximum size of saturated surface dry aggregate is 186 kg per cum ( for 50 mm slump without using superplasticiser ) .As per clause number 6.2.4 , page no 7 of IS 10262: 2019, Polycarbonate ether based super plasticisers reduce water content by 30 percent or above at appropriate dosages.

What is used for 1cubicmeter steel ? 1 Mix design of : M30 grade concrete 2 Type of cement used PPC cement ( supplied only with strength of 33 grade as per clause no 7.4.1 page no 2 of IS 1489 ). Water content with using appropriate dosages of super plasticisers =186 X 0.7 =130 kg/cum From figure 1 Page no 4 of IS 10262 : 2019 free water cement ratio required for the target strength of 38.25 N/mm2 is 0.42 for PPC (curve 2) which is less than the maximum value of 0.45 prescribed for mild exposure for reinforced concrete as per Table 5 of IS 456 :2000 hence OK Hence Volume of coarse aggregate and fine aggregate = 1 – (0.112-0.134–0.0015-0.005) = As per clause number 6.2.7 , Table 10 page number 10 of IS 10262 : 2019 . The maximum water-cement ratio to design M30 grade concrete can be found from Table 5-IS456 given above.

At the same time all are mentioned mix ratios. Maximum Nominal Aggregate Size: 20 mm: 4. And if the aggregate is dry the amount of mixing water shall be increased by an amount equal to the moisture likely to be absorbed by the Enter your email address to subscribe to this blog and receive notifications of new posts by email.Necessary cookies are absolutely essential for the website to function properly. how to find quantity of total concrete, cement bags and sand.
