Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.

weeks is required when the aggregate sources have been previously used, four weeks for new aggregate sources. Obtain this information from the Contractor and submit on the Concrete Mix Design Request (Form 2416). See 5-694.711 for an explanation on completing this request form and an example of a completed form.

Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. Aggregates are classified based on specific gravity as heavyweight, normal-weight, and lightweight.

MIX DESIGN In Hot Mix Asphalt, binder and aggregate are blended together in precise proportions. The relative proportions of these materials determine the physical properties of the HMA and ultimately how the HMA performs as a finished pavement. The design method for determining the suitable

Jul 06, 2015· This test is done initially for concrete mix design and later conducted periodically for mix proportion adjustments if it is suspected that the grading of aggregates has changed considerably. 5. Fineness Modulus. Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is.

A simple method of concrete mix design will normal weight aggregates for pumped concrete is described in the paper.

May 28, 2010· By Adam D. Neuwald. Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f' c) and the maximum water-to-cement ratio (w/c).These two values are inversely related, which means that as the water-to-cement ratio increases, the compressive strength decreases.
