Chapter 3: Mixing Water for Concrete Almost any natural water that is drinkable and has no pronounced taste or odor can be used as mixing water for making concrete. Drinkable Water is good for making concrete • Some waters that are not fit for drinking may be suitable for concrete making provided that they satisfy the acceptance criteria
3-1 CHAPTER 3 ASPHALT CONCRETE PLANTS Asphalt Concrete mixes made with asphalt cement are prepared at an asphalt mixing plant. Here, aggregates are blended, heated, dried, and mixed with asphalt cement to produce a hot mix asphalt (HMA). This chapter discusses the two most common types of asphalt plants.
Figure 3.3. Separate sumps for mixing and loading pad and secondary containment structure. See Table 3.1 to size sumps Center sump designs slope the concrete floor to the middle of the mixing and loading pad as shown in Figure 3.4. Portable pumps or suction hoses are placed in the depression to recover liquid.

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse ...

2013 1.0 3-1 CHAPTER 3 ACI CONCRETE MIX DESIGN AND ALLOWABLE FIELD ADJUSTMENTS ACI Concrete Mix Design In 1963 the Virginia Department of Transportation realized that a definite need existed to adopt a standard method of concrete design. Contractors, Producers, and the Department itself had used many varying methods of concrete designs.
Designing and Proportioning Normal Concrete Mixtures
•Generally there is a 3- to 4-inch slump concrete at the job site. Add 3 gallons of Super Plasticizer to the mix and you will get 7- to 8-in slump concrete without any water added. One hour later the concrete reverts to the original 3- to 4- inch slump.

There is a true or false quiz. One question asked whether it is necessary for all equipment for mixing and transporting concrete to be clean. Other question states that masonry filler units are not allowed to come into contact with concrete. Concrete must be deposited within 50 ft of its final destination to avoid segregation during handling.
CHAPTER 3 CONCRETE CONSTRUCTION LEARNING OBJECTIVE: Recognize the different characteristics associated with concrete form design and concrete mix design; recognize the procedures in batching concrete and estimate concrete construction and labor. Identify the procedures and methods associated with precast and tilt-up construction.

Concrete Mix A certain type of concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The strength of concrete is measured by pouring the mix into casting cylinders 6 inches in diameter and 12 inches tall. The concrete is allowed to set for 28 days. The concrete’s strength is then measured.
