Example 3 Raw material calculation for a given concrete mix ratio
A concrete mix has a proportion of 1:0.4:1.8:2.5 (P:W:S:G). In the powder content, 90% percent
is Portland cement and 10% is solid silica fume (SF). The concrete also uses 0.25% retarder and
1.5% superplasticizer. The absorption for sand is 1.2% and for coarse aggregate is 0.9%. The MC
(OD) is 2.5% for sand and 0.4% for coarse aggregate. The solid content is 35% in retarder and 40%
in superplasticizer. The SF used is a slurry with 50% of water. To cast 5 beams (100 × 100 ×
500 mm) and 18 cylinders (100 × 200 mm), how much of each individual ingredient should be
used (consider 5% extra amount)?

We require a mix with a mean 28-day compressive strength of 40 MPa the size of the member and the spacing of the reinforcement require a slump of 45 mm and a maximum size of aggregate of 28 mm. Portland cement type I is used with specific gravity of 3.15, dry-rodded unit weight of coarse aggregate 1750 kg/m³ and bulk specific gravity (SSD) of 2.55. The fineness modulus of fine aggregate is 2.8 and bulk specific gravity (SSD) of 2.5 ,No air entrainment is required. Neglect water absorption and moisture content of both aggregates. The aggregates conform to the ASTM C33-84 requirements for grading. Estimate the quantity of (cement, fine aggregate, coarse aggregate and water) for 1m³ concrete.
For a design a concrete mix which is going to be used in Muğla the 28-day compressive strength of the concrete is required to be 30 MPa and slump of the fresh concrete is specified as 8-10 cm. Maximum size of the aggregate is 25 mm. Other necessary data are given as: Specific gravity of cement = 3.1 Bulk specific gravity of coarse aggregate = 2.68 Bulk specific gravity of fine aggregate = 2.64 Absorption capacity of both aggregates is 1.5% Fineness modulus of fine aggregate = 2.8 Dry rodded unit weight of the coarse aggregate = 1600 kg/m³ According to ACI 211 and based on absolute volumes: What should be the weight of SSD coarse aggregate in kg's? What should be the amount of mixing water in kg's? What should be the water to cement ratio? What should be the volume of dry rodded coarse aggregate per unit volume of concrete?

Hydration of cement is exothermic process that generates heat. The table below shows the heat generate with different cement components. Which component is recommended to build a dam wall which is a large amount of cement block? a. None of the above b. C2S only which generate less heat and less thermal stress c. A mixture of Low heat cements to avoid thermal stress and high energy released and other factors should be considered. d. C3A because it generates large amount of heat and dry the block faster.
