formwork or tying of reinforcing steel Concrete fill can be rapidly placed without vibration with low shrinkage self-consolidating concrete No reinforcement inside the tube. CFT Construction: Commonly used in other countries
The surface area of a concrete slab or sand base is directly affected by its thickness. In the photo, you see two examples of a measured cubic foot.Since a cubic foot is measured by Length x Width x Thickness, a cube 1-foot long x 1-foot wide x 1 foot thick is therefore 1 cubic foot.
You can use the same formula for different mix proportions such as 1:1.5:3 etc. Here, we have used cubic meter unit but you can also calculate in cubic feet unit. Also Read – Concrete Mix Desi gn.
A concrete slab is commonly used as a base element in modern buildings. Often those slabs have steel reinforcement. Commonly, concrete slabs are between 4 and 20 inches thick and are used for a purpose of floor and ceiling construction. Thinner slabs can be used for exterior paving. Before any pour you need to know how much concrete will be needed.
Required Quantity Of steel for 1m3 concrete is. Generally we are consider 100kgs steel per cum of concrete for calculation which will give the rough quantity of steel required for project. Steel quantity for different -2 structural members are. for columns 2-3% for slabs 0.5-1.5% for beams 1-1.5% for piles 2-5%. Thanks for the A2A. Best Of Luck ...
Aug 25, 2018· 1) State of steel i.e. solid steel or liquid steel because densities of steel is different in different steel. 2) Grade of steel i.e. it's chemical composition. But anyways , in general. Density of liquid steel = 6900kg/m3. Density of liquid steel = 7800kg/m3. So 1 m3 of liquid steel makes 6900kg. Whereas 1 m3 of solid steel makes 7800kg.
The second step is to determine the component of structure for which the RCC rate analysis is required, as the quantity of reinforcement steel varies with slabs, beams, columns, foundation, RCC Roads etc., though the quantity of other materials like sand, coarse aggregate and cement remain the same with the same mix design (mix proportion) of concrete.

Sep 22, 2012· Lightweight concrete weighs less than 120 pounds per cubic foot. These values are highly dependent on the density of the coarse and fine aggregates, void space ratios, and other mix parameters. Depending on the amount of steel, for many applications, an additional 5 pounds per cubic foot is often used in estimating.
So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete. Method-1: DLBD method to determine material requirement for 1 Cum concrete. The DLBD (Dry Loose Bulk Densities) method is an accurate method to calculate cement, sand and aggregate for a given nominal mix concrete.
Following table shows unit weight of materials used at construction site. Please note this is for reference purpose only and may vary from place and type of material.
This will vary according to how much reinforcing steel per yard of concrete is used in the product. 200 pounds of reinforcing steel per yard would have resulted in a final density of 146.28 pounds per cubic foot.

For example, let's calculate how much concrete is needed for a 5-inch thick rectangular driveway, 60-feet long (length) and 18-feet wide (width). The area of the driveway is 1,080 square feet (60-feet x 18-feet). According to the table above, one cubic yard of concrete placed …
Concrete-Filled Steel Tubes (CFTs) are composite members consisting of an steel tube infilled with concrete.In current international practice, CFT columns are used in the primary lateral resistance systems of both braced and unbraced building structures.
Step-1: Calculate the Volumes of material required in 1 Cum concrete. The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concrete is 1.54. So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete
Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M7.5, M10, M15 and M20. if you don’t want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.

What equation should I use to find out how much concrete I need? How to calculate concrete: Determine how thick you want the concrete; ... 100 x .33 = 33 cubic feet; 33 x .037 = 1.22 cubic yards; Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x ...
All concrete is estimated in cubic yards (one cubic yard = 27 cubic feet). For large concrete jobs - four cubic yards or more - the concrete should be delivered by a ready-mix truck. It’s also possible to haul fresh concrete to your site in special two-cubic-yard trailers provided by concrete producers.
its depend on dia of bar used in concrete for example the weight of steel of one meter rod having six mm dia is two hundrerd and twenty grams and ten mm dia is six hundrerd and twenty grams etc you can find weight of different bars having different diameters by this formula = (d*d)/one hundrerd sixty two
so first 10cum converted into CFT that is 353.10(10/0.02832)=353.10 Cft x 7 lbs/Cft =2471.70 then convert in to Kg so =1121.16 Kg is the answer.so in 10cum qty of concrete required 1121 kg steel. Was this answer useful?
