Bleeding, Screeding, Leveling, Edging, Jointing, Floating, Troweling, Broom Finish

Concrete Cure Time

28 days for full strength

Pre Cast Concrete Advantages and Disadvantages

Pros: manufactured in a controlled environment, efficient quality control and management, does not require a large land area, and how weather conditions are not a factor.

Cons: may not always be delivered on time for construction time, delivery costs, and needs a small error margin to perfectly fit the entire design.

Cast in Place Concrete Advantages and Disadvantages

Pros: no delivery needed, versatility with computer modeling, and allowing builders leeway to design precise and customizable forms for the structure.

Cons: Its disadvantages though are its lengthy time set-up, space usage, and uncertainty of quality, and the use of intense labor.

CMUs in Built Environment

Easy, cheap, lightweight, durable, fire-resistant

Clay Masonry Units in Built Environment

Easy, cheap, lightweight, durable, fire-resistant

Frogged and Cored Brick purpose

Used in building construction

CMU and Brick Modular Dimensions

Standard sizes for industrial use

Architectural Design per CMU Course

If you have an even measure on the design, you could add either 8” or 0” to the design. If you have an odd measure, you will add 4”.

Vertical Bricks per CMU

3 bricks per CMU

Weep Holes

Drain water from buildings

Mortar vs Grout

Mortar for masonry, Grout for ceramics

Types of Mortar

M, S, N, O

Type M Mortar

reinforced masonry or anything else that requires high strength

Type S Mortar

reinforced/nonreinforced masonry or anywhere where flexible strength is needed

Type N Mortar

most general situations and anytime high/lateral strengths aren’t needed.

Type O Mortar

mostly interior
