Summary

The Causes and Prevention of Concrete Surface Imperfections

Workshop Description/Agenda

Learning Objectives
Learning Objectives * You will be able to discuss materials for concrete. * You will be able to describe concrete mixtures for flatwork. * You will be able to explain base preparation and form work. * You will be able to identify troubleshooting slab defects.

Benefits
Understand the common causes of concrete imperfection and how to minimize or prevent them. It is to the credit of concrete that so few complaints are received on the vast amount of construction put in place. While it is easy to determine the properties of the hardened concrete that will be suitable for the intended purpose, great care is required throughout the entire construction process to ensure that the hardened concrete actually has the desired properties. When a blemish appears on the surface of a concrete slab it will likely be one of these dusting, scaling, crazing, cracking, plastic shrinkage cracks, thermal cracking, blisters, discoloration, aggregate popouts, alkali aggregate reactions, and deicers. These deficiencies, caused by specific factors that are explained in this information, can be minimized or prevented by adhering to proper construction methods.
