of raw materials. For example, the cement industry began to address climate change in the mid-1990s—one of the first industries to do so. Over the past 40 years, U.S. cement manufacturers have reduced the amount of energy required to produce a ton of cement by over 40 percent. The industry also has reduced its use of traditional fossil ...

Our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. Simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) You can build up a concrete calculation for complicated areas by adding additional shapes of each type.

Calculating the amount of mortar needed for the joints in a concrete block wall will vary depending on the mortar mix you use. On average it takes about three bags of cement for every 100 blocks. Divide the number of blocks being installed by 33.3 to calculate how many bags are needed.

amount of water required for complete hydration of portland cement This point-of-view article discusses the amount of water that would be needed to completely hydrate portland cement. The ratio of the volume of water to the volume of cement is critical in the chemical reaction that causes concrete to stiffen, harden and develop strength.

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.

Apr 18, 2018· Determining with some precision the amount of concrete you'll need to pour a slab for any kind of home improvement project will save you time, money and effort. After all, if your estimate is incorrect, you could wind up with a concrete mixer truck delivering less than you need, resulting in an additional expense for a second delivery.

Jul 09, 2014· To do this multiply the cubic meters by 1.5 which will give you the weight of the concrete required in metric tonnes. With a standard 3 in 1 sub ground concrete mix, (3 parts ballast to 1 part cement), each 850kg bag of ballast will account for 1150 kg of concrete due to the addition of cement …

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. Please use the calculator below to give you some estimate of the concrete amount.;

Apr 12, 2018· M20 => 1:1.5:3 (CEMENT : SAND : AGGREGATES) Assume volume of concrete = 1m^3 step 1:- Calculate dry volume of concrete Dry volume = (Wet volume x 1.54) then, Dry volume = 1 x 1.54 = 1.54 m^3 Step 2:- Calculate quantity (Volume) of cement Quantity ...

Concrete CO 2 Fact Sheet JUNE 2008 4 greenhouse effect resulting from these greenhouse gases. Water vapor, the most abundant greenhouse gas, is not affected by human activity.1 • Atmospheric concentrations of CO2 are expressed in units of parts per million by volume (ppm).

A simple method of concrete mix design based on flexural strength for normal weight concrete mixes is described in the paper. INTRODUCTION: Usual criterion for the strength of concrete in the building industry is the compressive strength, which is considered as a measure of quality concrete.

Concrete basically consists of Portland cement, water, and fine and coarse aggregates. A pozzolan material, such as fly ash, may be added to the concrete mix as a partial substitute for cement. The curing of the concrete is a chemical reaction of the Portland cement and water, which causes the concrete to shrink and crack.
