light concrete formula
Concrete mixes are variable, and specific to certain applications. As a general rule, the larger the final piece the larger the aggregate. (For descriptions of aggregates and additives see the materials page.) These are basic mixes that I have used and developed over time and work well in terms of plasticity, compressive strength, density and finishing characteristics.
Formulas for Lightweight Concrete. Fernando Martinez Lewels has a M.S.C.E degree from the University of Texas at El Paso. He is now working with the Agartif company in Chihuahua, Mexico (about 170 miles from El Paso Texas).
Modulus of Elasticity of Concrete. Modulus of Elasticity of Concrete can be defined as the slope of the line drawn from stress of zero to a compressive stress of 0.45f’ c. As concrete is a heterogeneous material. The strength of concrete is dependent on the relative proportion and modulus of …
A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.
How to Calculate Lightweight Concrete Mixes. Standard concrete mixtures consist of four elements: Portland cement, sand, gravel aggregate and water. In many instances, a lightweight concrete is used to achieve a specific weight-per-square-foot. Lightweight concrete is achieved by substituting a lighter weight material for the gravel aggregate....
In buildings, light-weight concrete will produce a higher fire rated structure. It also provides higher R-Values of wall elements for improved insulation properties. These two reasons are why it is used for lightweight concrete floors, lightweight concrete roofing and lightweight concrete block. Lightweight aggregates require wetting prior to ...
The elastisitymodulus or E-modulus is a property of a material (like concrete or steel) whichs tells how much tension is needed to make it a little bit longer or shorter (when you pull at 2 ends of a steal beam it’ll be a bit longer then when you press it together).

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³ ...
Cellular Concrete is a cementitious paste of neat cement or cement and fine sand with a multitude of micro/macroscopic discrete air cells uniformly distributed throughout the mixture to create a lightweight concrete. It is commonly manufactured by two different methods. Method A, …
ACI-318-08 CODE REQUIREMENTS FOR DESIGN OF CONCRETE FLOOR SYSTEMS1 This Technical Note details the requirements of ACI318 -08 for design of concrete floor systems, with emphasis on post-tensioning and their implementation in the ADAPT Builder Platform programs.
Apr 18, 2018· Concrete foam was originally used as insulation in the 1920s. The material was brought into home construction projects in the '80s where it was used as an inexpensive patch alternative for walkways and walls. It was also found easy to manipulate and form molds that were inexpensive to make and light enough to move around.
Weight of the concrete per volume of concrete. Automatic calculator for the specific unit weight of a volume of concrete in pcf, lb/ft^3, lb/yd^3, kg/m3, fresh wet concrete mix and dry cured hardened concrete. Weighing concrete in tonnes per cubic meter or kilograms kg, lb pounds per cubic foot or yd yards. Online convert and calculate how heavy is any volume of normal concrete 150 lbs/ft^3 ...
May 09, 2018· Lightweight concrete may not be as structurally sound as traditional concrete, but it can be useful in some projects where weight is more important than strength. To make this concrete, combine 8 parts cement, sand and lightweight aggregate with 5 parts water.
CIP 36 - Structural Lightweight Concrete WHAT is Structural Lightweight Concrete? WHY Use Structural Lightweight Concrete? HOW is Structural Lightweight Concrete Used? Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb/ ft 3 (1440 to 1840 kg/m ) compared to normalweight concrete with a density in the
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.
The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of 0.55, which translates to 55 pounds of water for every 100 pounds of cement.
CHAPTER 7 ENGINEERING PROPERTIES OF STRUCTURAL LIGHTWEIGHT CONCRETE 7.0 Introduction Comprehensive reports detailing the properties of Lightweight Concrete and lightweight aggregates have been published by Shideler (1957), Reichard (1964), Holm (1983 and 2006), Carlson (1956), and Valore (1956, 1980). The first three
63 lb. 2/3 cu. ft. Lightweight Concrete Mix is rated 4.0 out of 5 by 2. Rated 4 out of 5 by HomeDepotCustomer from in the last 3 years, i have purchased over... in the last 3 years, i have purchased over 300 bags. the thing that i hate the most about it is the price has risen to the point where it is totally out of line.
Lightweight Concrete Planters Why buy expensive concrete planters when just a bit of DIY know-how and leftover foam packing materials are all you need to create your own stylish and lightweight planters.
Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), aircrete, foamed concrete, foamcrete, cellular lightweight concrete or reduced density concrete, is defined as a cement based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar.
Properties of Lightweight Concrete. The most significant property of lightweight concrete is reduced weight at no sace in strength. Structural lightweight concrete available today are rotary kiln expanded shale, clay or slate (roughly 80% of structural use) and sintered expanded shale or clay (20%).
The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
Jul 27, 2018· To make cellular lightweight concrete mix water with dry mix (cement and limestone compound) add aerated agent and pour the admixture in the mold. In case you need exact recipe visit our website ...
The basic foam concrete is made from mixing aqueeous foam which is produced from generators (IFG) into Slurry of Cement, fly ash OR sand, water and other additives in a precise mixing in foam concrete mixer(IFM) for accurate mixing without disturbing its original chemical and physical properties. Advantages • Light in Weight • High Thermal ...
Everything will be the same as a basic concrete tile or stone mix formula except for the sand, which is the variable. You may want to experiment with different lightweight aggregates, if they are readily available to you locally. The use of lightweight aggregate other than Perlite, will affect the weight and strength of your stone.
The formula for concrete calculations is (length x width x depth) divided by 27. The result of this formula provides the number of cubic yards of concrete needed. The measurements must be in feet in order for the equation to work.
Quickly calculate concrete slab and footing pours by entering the depth, width and length to find the number of cubic yards or bags of concrete needed for your project. Give these calculations to your ready-mix supplier or use them to estimate how many 40, 60 or 80 lb. bags of concrete to buy.
Lightweight concrete blocks are made by adjusting the ratio of the concrete mix with a lightweight aggregate, like Perlite. With that in mind, the amount of aggregate substitution depends on the type of project. If you are using the concrete indoors or in a place unaffected by weather, then a full lightweight mix is acceptable.
The concrete cubic yard formula is provided here as a quick review for professionals or amateurs contemplating a new concrete project. A bags concrete calculator is also included, as is how much concrete weighs, and as well a cubic yard calculator for foundations.
