What is the Basic Process function in Coagulation/Rapid Mix?

What is the process by which one can ensure that a given mixing process for a particular sachet type is yielding a homogeneous mix?

What are the purposes of doing the specific gravity and absorption of coase aggregates? why?

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?

29 - please show complete solution, thanks!

Table P5.27 shows the grain size distributions of aggregates A, B, and C. The three aggregates must be blended at a ratio of 15:25:60 by weight, respectively. Using a spreadsheet program, determine the grain size distribution of the blend. TABLE P5.27 Percent Passing Sieve Size, mm 25 19 12.5 9.5 4.75 1.18 0.60 0.30 0.15 Aggregate A 100 100 100 77 70 42 34 28 20 Aggregate B 100 85 62 43 24 13 Aggregate C 100 100 84 51 29 19 18 14 9.

4. A sample of fine aggregate weighs 501.2 g when SSD and 491.6 g when OD. The flask weighs 540.6 g when filled with water and 843.1 g when filled with the aggregate sample and water. Calculate the bulk specific gravity, apparent specific gravity, and percent absorption.

determination of moisture content and surface moisture of aggregates is a method to determine wether the material is good or not, what is the essence of this  methods in construction? Explain.

A mix design requires 1160 kg/m3 of coarse aggregate (in dry condition), 599 kg/m3of fine aggregate (in dry condition) and 148 kg/m3 of water. The absorption capacityof the coarse aggregate is 0.4 % while the moisture content is 1.5%. The absorptioncapacity of the fine aggregate is 0.4 % while the moisture content is 4%. Pleaseanswer the following questions based on information given. a. What is the amount of Moist Coarse Aggregate? b. What is the amount of SSD Fine Aggregate? c. What is the amount of Moist Fine Aggregate? d. What is the amount of water after adjusting for moisture?

Aggregates from three sources having bulk specific gravities of 2.753, 2.649, and2.689 were blended at a ratio of 70:20:10 by weight, respectively. What is the bulk specific gravity of the aggregate blend?
