Concrete Technology Part 3: Placing TSYH 3232

Upon successful completion, the student will be able to:

Module 1 - Batching, Mixing, Transporting and Handling Concrete

• Define the terms related to the concrete production including, batching, mixing, agitation, transportation, conveying, remixing, etc.
• Compute the tolerances and determine the requirements and limitations for remixing concrete.
• Identify the methods and equipment used to handle concrete, and list the advantages and points to be aware of for each of the following; truck agitator, truck mixer, chutes, belt conveyors, buckets, etc.

Module 2 - Placing and Finishing Concrete

• Identify the field tests for acceptance of concrete on the job site.
• Differentiate between proper and improper methods of placing and consolidating concrete.
• List and describe the procedures for finishing a concrete slab.
• Discuss control joints and determine the spacing of control joints given the required job placement conditions.

Module 3 - Curing Concrete

• State the objectives of curing and discuss the effects of interruption of normal curing on the strength of concrete.
• Recommend an appropriate curing method and the materials to be used based on the size, shape and economics of the job.
• Recommend an appropriate curing period based on the concrete used and the type of construction project.

Module 4 - Hot and Cold Weather Concreting

• Identify the conditions and temperatures, and prescribe measures to be undertaken to minimize plastic shrinkage cracking, strength loss, etc., during hot weather concreting.
• Identify and recommend methods to either heat or cool the materials used to batch, place, and cure appropriate temperature concrete.
• Calculate the appropriate thickness of insulation, duration and heating requirements to facilitate cold weather curing.
