ACI 548.6R - Polymer Concrete: Guidelines for Structural Applications
January 1, 2019 - ACI

INTRODUCTION Polymer concrete (PC) has been used in structural applications where strength, stiffness, durability, and ease in molding provide an advantage over other materials. Many types of reinforcement can be used with PC. This guide presents the structural uses of PC. Polymer...

ACI 228.1R - Report on Methods for Estimating In-Place Concrete Strength
January 1, 2019 - ACI

In-place tests are performed typically on concrete within a structure, in contrast to tests performed on molded specimens made from the concrete to be used in the structure. Historically, they have been called nondestructive tests because some of the early tests, such as rebound...
