Pour U-MIX Concrete Mix into a clean wheelbarrow, mortar box, or mixing bucket. Form a crater in the center of the dry concrete mix. Pour clean potable water into the crater at a rate of one quart per 20 pounds of concrete mix. Work the mix with a shovel or hoe adding water as needed to achieve a stiff moldable mixture. Use only enough water to ensure all the dry concrete mix is wet and Concrete and screed mix designs can both be altered to meet your requirements. We can adjust the ratios or introduce admixtures to give the material different qualities. If you need a lightweight concrete or screed, for example, an aggregate like LYTAG could be used in the mix. Or, for a higher compressive strength, we can adjust the water-cement ratio as needed. The benefits of concrete and

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened.The strength concrete is inversely proportional to the water/cement ratio.

This Nominal mix concrete may be used for concrete of M-20 or lower than the M-20. IS: 456-2000 has recommended that the minimum grade of concrete shall not be less than M-20 in reinforced concrete work. The Nominal mixes can be used with the permission of engineer-in-charge for the important concrete works. Which however is likely to involve a higher cement content. When the size of
Concrete Mix. This is a mixture of aggregates, cement and water that when mixed creates a workable form. Mortar Mix. This is a blended mixture of sand and Type N masonry cement the tis commonly used for laying brick, stone or block . Parking Bumpers.

IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2. The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively. The proportions
Example • Design a Concrete mix for M 25 grade as per IS 10262 for the following data: • Characteristic Compressive Strength in the field at 28 days 25 N/mm2 • Maximum Size of Aggregate= 20 mm • Degree of Workability 0.9 CF • Degree of Quality Control= Good • Type of Exposure = Moderate 65.
GRADE OF CONCRETE. Concrete of Grade is a mixture of Portland cement, water, and coarse and fine aggregates. It consolidates into a hard mas because of a chemical reaction called hydration between cement and water. Proportioning a concrete mix for a given purpose is thus the art of obtaining a suitable ratio of the various ingredients of concrete with the required properties at the lowest cost.
Requirements for concrete mix design. The grade designation giving the characteristic strength requirement of concrete. The type of cement influences the rate of development of compressive strength of concrete. Maximum nominal size of aggregates to be used in concrete may be as large as possible within the limits prescribed by IS 456:2000. The cement content is to be limited from shrinkage
