Length = 2.50m
Cement = 50kg/bag
Using Class A concrete mixture, what is the volume of sand, cement, gravel and water needed?
Step by step
Solved in 2 steps
- Calculate the slump of fresh concrete mix if you know: 1. W/C =0.47 2. Sand = 648 Kg/m3. 3. Gravel = 1056 Kg/m?. 4. Dry rodded mass of coarse aggregate is 1650 Kg/m?.A batch of concrete consisted of 200 lbs. fine aggregate, 350 lbs. coarse aggregate, 94 lbs., cement and 5 gallons water. The specific gravity of sand and gravel may be taken as 2.65 and that of the cement as 3.10. How much by weight of cement is required to produce one cubic yard? Final answer must be in pounds.Estimate the total amount of cost for concrete works (class “B”) based from the following given: 10-pcs of F1 (1.2m x 1.2m x 0.3 m) 10-pcs of C1 (0.3 m x 0.3 m x 4.1 m) Floor area of 100mm thk slab-on-grade = 53 sq.m The cost of cement (40kg per bag) = 210 per bag. The cost of sand is 710 per cubic meter. The cost of gravel is 1900 per cubic meter.
- Calculate the weight of cement, fine aggregate (sand), coarse aggregate (rock) and gallons of water to mix a 1:2:4 concrete mix design ratio. The structure is a small utility pad that is 5’ x 5’ and is 5 inches in depth. Make sure you make enough, use the 10 percent rule. Use a water to cement ratio of 0.50. Weight of Concrete = 150 lbs per ft3 1 gallon of water = 8.34 lbs. How many yards of concrete were required?From the following figure find the cement, sand and gravel if there are 8 columns, using class "A" mixture.Situation 2. Given the following data for a concrete mix:Target Concrete Strength = 40 MPaSlump = 75 mm to 150 mmWater – Cement Ratio = 0.48Unit Weight of Concrete = 23.4 KN/m 3Water Content = 180 Kg/m 3Entrapped Air = 1%Fine Aggregate = 33% of the total volume of the aggregatesSpecific Gravity of Materials:Cement = 3.15Fine Aggregate = 2.68Coarse Aggregate = 2.64 4. Calculate the required weight (kg) of cement and water per cubic meter of concrete. A. 530 C. 632 B. 587 D. 555 5. Calculate the required weight (kg) of fine aggregates per cubic meter of concrete.

WF=3% No. of 40kg bagse) Find the volume required for the fine aggregate if WF sand = 15%, in cubic metersf) How many pieces of 10mm diameter x 6 meters long rebar must be ordered? In piecesg) What will be the total mass of the reinforcing steel bars, in kilogram? In kilograms
- write small introduction about (cement, fine aggregate, coarse aggregate ) also about superplstizer adding in concreteA box measuring 50 cm x 50 cm x 50 cm is filled to the top with dry coarse aggregate of mass 187.5 kg. The water absorption and specific gravity of the aggregate are 0.5% and 2.5, respectively. The maximum quantity of water (in kg, round off to 2 decimal places) required to fill the box completely is brisA batch of concrete consisted of 200 lbs fine aggregate (sand), 400 lbs coarse aggregate(gravel), 95 lbs cement, and 5 gallons of water. The relative density of the sand andgravel may be taken as 0.65 and that the cement as 3.10 What was the total volume ofconcrete produced?
