Maximizing the amount of aggregate, to a certain extent, improves the quality and economy of the mix. True or False. Explain 3.A concrete mix design uses coarse aggregates with NMAS of 19 mm. Fineness modulus of 2.8 and DRUW of 135 lb/ft^3. What is the mass of Coarse aggregates in the mix?
- Give any two examples of samples of different types of aggregates and note the different shapes,textures and sizes. Discuss how each type might affect the concrete mixture.what is the effect of bulk specific gravity, bulk specific gravity (SSD), apparent specific gravity, and percent absorption to concrete mix? what is the range of these four to fine aggregates and coarse aggregate. If the result of these four is low or high, what is your recommendation?A concrete aggregate mix must contain at least 31% sand by volume for proper batching. One source of material, which has 25% sand and 75% coarse aggregate, sells for $3 per cubic meter (m3). Another source, which has 40% sand and 60% coarse aggregate, sells for $4.40/m3. Determine the least cost per cubic meter of blended aggregates.
