In grade 25 concrete, which typically has a mix ratio of 1:1:2 (cement:sand:aggregate), approximately 0.5 cubic metres of sand is required per cubic metre of concrete. Since the density of sand is about 1,600 kg per cubic metre, this translates to around 800 kg of sand needed for one cubic metre of grade 25 concrete. This amount can vary slightly based on the specific mix design and moisture content of the sand.
One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.
For M20 grade concrete mix proportion=1:1.5:3 And dry volume factor is 54 percent. Hence, we required to find quantities for 1.54 cum concrete. cement required=(1/5.5) x (1.54)=0.27 cum, Sand required=(1.5/5.5) x (1.54)=4.2 cum, Stone chips required=(3/5.5) x (1.54)=0.84 cum.

Full basement is the grade of concrete that is laid for foundation.

A concrete valley gutter slip form machine is equipped with adjustable side plates that match the desired grade profile. As the machine moves forward, a cutting shoe at the bottom of the slip form trims and smooths the concrete to achieve the required grade. The machine's sensors and controls ensure accuracy and consistency in cutting the grade as it progresses along the length of the gutter.

concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
To determine how many 50 kg cement bags are required for 1 cubic meter of Grade 30 concrete, we need to break down the mix ratio and calculate the cement content based on that. Grade 30 Concrete Mix Ratio Grade 30 concrete typically has a mix ratio of 1:2:3 (Cement: Sand: Aggregate) by volume. This means: 1 part cement 2 parts sand 3 parts aggregate (gravel) However, the actual proportion of cement required can vary slightly depending on the specific mix design used by a contractor or engineer. For standard Grade 30 concrete, the cement content is typically around 350 to 400 kg per cubic meter. Since each cement bag weighs 50 kg, the number of bags required for 1 cubic meter of Grade 30 concrete would be: Number of bags = 350 kg / 50 kg = 7 bags
