Fundamentals of Concrete

The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65, 60-lbs of fine aggregate with Gs = 2.63, 25-lbs of cement, and 12-lbs of water the absolute volume is computed as follows:

Concrete Mix Design: Proportioning

For roughly 100 years, we have been using the absolute volume mix design method. This method differs from the 1-2-4 method by using math to ensure a mix design provides the desired yield no matter what materials are used. Prior to continuing, it is a good idea to read American Concrete Institute 221R,...

How to determine concrete yield

design stage. It is not unusual to encounter mix designs which simply will not yield 27 cubic feet of concrete per cubic yard of concrete ord e r ed. When the concrete pro-ducer re c e i v es the approved mix design, he should check it for yield. This can be accomplished by applying the formulas in the preceding section. If the mix design

Mix Design - Self-consolidating Concrete

Mix Design . SCC looks very different from conventional concrete while mixing. Concrete producers must “retrain their eyes” for this very fluid mixture as it turns corners and fills forms. Traditionally, concrete with the fluidity of SCC has had a very high water-to-cement ratio, which would lower compressive strengths and compromise ...

EXAMPLE USING ABSOLUTE VOLUME METHOD

Calculate the absolute volumes. For one cubic yard of air-entrained concrete, the volume of the air can be determined by simply multiplying the air content by 27. For this mixture, the air content from Step 1 above is 5 percent; therefore, the volume of air is 0.05 x 27 = 1.35 cubic feet.

Yahya Ghasemi Print III

first step in making concrete is its mix design and deciding the type and amount of constitutes used in the production of concrete which should fulfil the requirements of the final product. Mix design models are commonly used for the purpose of proportioning concrete ingredients while anticipating the properties of the final product.

MASSIVE CONCRETE PLACEMENTS

ACI 207 defines mass concrete as: “… any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from the hydration of the cement and attendant volume change to minimize cracking”.
