Civil Engineering Classes Cement, Aggregate & Sand quantity are used in 1:1.5:3 concrete.....  Dry Volumn Concrete = Approximate 54 % to 57 % more than Wet Volumn Concrete. so, considering the factor of safety ranging from 1.54 to 1.57 to counter that shrinkage.  i.e., Volume of dry concrete = 1.54 to 1.57 times Volume of wet concrete

How to calculate land area at site The Solution is Heron’s Formula: If there is a triangle having three sides (a, b and c), and if you know the measurement of the three sides, then Area =  Where s is semi perimeter And s = (a + b + c)/2 Let’s suppose there is a land having irregular shape and we need to find the area of the land. In triangle ABD AB (a) = 3 m BD (b) = 4 m AD (c) = 5 m S = a + b + c /2 = (3 + 4 + 5)/2 = 6 m Area =  In triangle BCD BC (a) = 3 m CD (b) = 3 m DB (c) = 4 m S = (3 + 3 + 4)/2 = 5 m Area = 4.47 m 2 In triangle ADE Area = 3.8 m 2 Total area = 6 + 4.47 + 3.8 = 14.27 m 2 To get more details, go through the following video tutorial.

How to calculate the cement, sand quantity for plastering how to calculate the cement sand quantity for plastering. Let us suppose, Mortar ratio = 1:6 where 1 is cement and 6 part is sand. Plaster thickness = 12 mm = 0.012 m Cement density = 1440 kg/m 3 1 m3 = 35.3147 ft3 Suggested Plaster Thickness 12 mm for internal walls or brick wall plain surface 15 mm for 4” or 9” brick wall rough surface 20 mm for two plaster layers normally utilized for external walls Mortar Wet volume = 1 x 1 x 0.012 = 0.012 m 3 Mortar Dry volume = 0.012 x 1.30 = 0.0156 m 3 Mortar Dry volume (sand + cement) = 30 – 35 % greater than wet volume = wet volume x 1.30 Concrete Dry volume (aggregate + sand + cement) = wet volume x 1.54 As we know that mortar ratio = 1:6, from which 1 + 6 = 7 = sum of ratio Amount of cement in plaster = 1/7 x 0.0156 x 1440 = 3.21 kg Also in bags = 3.21/50 = 0.064 bag = approximately 1 bag Amount of sand in plaster = 6/7 x 0.0156 = 0.0133 m 3 Sand ...

Calculation Of Materials For Different Mix Ratio: Quantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete. In our previous article, we have already discussed how to calculate bricks in a wall.  Today we will discuss how to calculate quantities of materials for different mix ratio of concrete. (Dry mix method) We will calculate quantities of materials for 1 m3 concrete (By volume). Let us assume the mix proportion is 1 : 2: 4 (cement:sand:stone =a:b:c)   Volume of wet concrete = 1 m3 Volume of dry concrete = 1 × 1.54 = 1.54 m3 What Is 1.54 Given Above in Figure Calculation For Cement: Formula, Cement = (Volume of dry concrete/a+b+c) × a = (1.54/a+b+c) × a = [(1.54/1+2+4)] × 1 = 0.22 cum Now density of cement = 1440 kg/cum ∴ Volume of cement = 0.22 ×  1440 =316.8 kg. As we know, 1 bag of cement contains 50 kg of cement . ∴ Cement bags requir...

◾1 bag of cement = .0347 cum ◾1 sqm = 10.76 sqft ◾1 inch = 25.4 mm ◾Weight in Kilograms of Mild Steel (Sheet,grill etc.) = (Volume x Density of Mild Steel) = Length x Width x Thickness x 7850 kg/cum. Eg. 2.5 m x 1.25 m x .001 m x 7850 = 24.53 KGs……….. [ Keep a notice on the units ] ◾1 tonne = 1000 KGs ◾1 quintal = 100 KGs ◾1 Acre = 43560 sq. ft = 4046.46 sqm ◾1 cum = 35.32 cuft ◾Unit Weight of Steel Bar = D^2/162 where D is the diameter of the bar. Eg. 12 mm dia bars, unit weight = 12*12/162 = 0.89 kg/m. [Unit weight in this case is the weight of steel bar per meter ]. ◾1 ton and 1 tonne are different things. 1 ton is US ton which is 907.18 KGs. 1 tonne or 1 MT(usually referred as MT in BOQs) is 1000 KGs. ◾In some cases earthworks will be in % Cum wherein you will need to divide the amount by 100. Eg. Earth work in excavation of foundation trenches or drains, Qty = 24295 %cum Rate = Rs. 9161.6 Amount = 24295*9161.6/100. Standard conversion factors INCH = 25.4 MILLIMETRE...

Q.  What is 1.54 in Concrete during  the calculation of quantity of  sand, cement and aggregate? Ans.Here in this image the presenter of this presentation portrays what is 1.54 factor in concrete during calculation of wet volume to dry volume. ✔ Keep Reading this Blogsite regularly For the Deep Knowledge of Civil Engineering

✅ Let us consider the nominal mix is 1:2:4 Wastage of cement during handling is considered as 2% Output of mix is considered as 67% To achieve 1 cum output, we need drymix 1/0.67 = 1.49 say 1.50 cum. Now add the wastage of 2%, i.e (1.50 + 0.02) = 1.52 cum. Volume of cement = (cement/cement+sand+aggregate) × Total material =(1/1+1+4) × 1.52 =0.2171 cum Now, Density of cement is 1440 kg/cum Weight of 1 bag cement = 50 kg. Therefore volume of 1 bag cement = 50/1440 =0.0347 cum. ∴No. of cement bags required in 1 cubic meter= 0.2171/0.0347 = 6.25 bags. 🔗 Note: Same formula can be used for calculating cement for other nominal mixes also.
