Results from a controlled slab-on-grade experiment relating drying shrinkage, curling and joint opening are presented. The experimental program involved instrumented slab strips maintained in a controlled environment for 1 year. The data includes sta

Degradation due to cyclic freezing and thawing is a major durability problem in the concrete industry. Since the early 1930s, air entrainment by surfactant chemistry has been used to improve the resistance to freezing and thawing of concrete. Despite

Historically, ring tests have been performed to determine the time for concrete or mortar specimens to crack under restrained shrinkage. When the concrete or mortar ring deforms due to shrinkage, the steel ring restrains the material and tensile stre

The controlling factor in designing non-load bearing masonry walls, such as those used in Kuwait, is the lateral resistance to wind loads. To ensure safety of the walls, data is needed on the flexural strength characteristics of walls constructed wit

The masonry walls used in building construction in Kuwait are non-load bearing. Traditionally, normalweight concrete blocks have been used throughout the region. However, with the enforcement of the Kuwaiti energy conservation code, autoclaved aerate

This paper outlines a testing and analysis procedure to quantify behavior of concrete under restrained shrinkage ring specimens. Cracking resistance is found to depend not only on shrinkage potential and tensile strength, but also on shrinkage rate a

Specification of proper criteria for concrete performance is necessary to eliminate shrinkage-related cracking. The aim of the analysis presented herein is to develop a rational basis for determining the appropriate concrete performance characteristi
