Forty mass-concrete mixtures were made with natural sand, 20 containing crushed limestone coarse aggregate and 20 containing natural gravel coarse aggregate. The coarse aggregate was 6-in. maximum size and was processed into eight gradings. Tests were made to determine the degree of suitability of this presently widely used grading formula. (Author).

Download Impact of Aggregates Sizes on Properties of Concrete Book in PDF, ePub and Kindle
Concrete is a composite construction material made primarily with aggregate, cement, and water. There are many formulations of concrete, which provide varied properties, and concrete is the most used man-made product in the world. Concrete is widely used for making architectural structures, foundations, brick/block walls, pavements, bridges, dams, pools/reservoirs, even boats etc. There is a general view that the size of coarse aggregate affects only the properties of fresh concrete and it is impact on hardened properties is insignificant. This book presents the impact of different sizes of coarse aggregate on fresh and hardened properties of concrete. While slump cone test evaluated the fresh concrete properties, compressive strength test determined the hardened state properties by using concrete mixtures that proportioned with three types of cements. Graded coarse aggregates with maximum aggregate size were selected for this experimental program for each cement. The results show that while the coarse aggregate size influences the slump, it is not relevant to compressive strength. The latter properties are governed by (w/b) ratio, cement type and cement content.

The purpose of these tests was to determine the effect of various fine aggregate gradings, ranging from very fine to very coarse, upon the following properties of concrete containing coarse aggregate graded from the No. 4-sieve size to 6 in. and having a cement content of 2.5 bags per cu yd: bleeding, air-entraining admixture requirements, water-cement ratio, compressive strength, resistance to accelerated freezing and thawing, and drying shrinkage.

Download Effect of Larger Sized Coarse Aggregates on Mechanical Properties of Portland Cement Concrete Pavements and Structures Book in PDF, ePub and Kindle
ODOT is continually searching for ways to improve the cost efficiency of Portland cement concrete without sacrificing concrete strength and stiffness. Because Portland cement is easily the most costly material used in normal concrete, limiting the amount of cement used is the quickest way to achieve cost effectiveness. In addition, limiting the cement content will also help to prevent dimensional instabilities in concrete such as shrinkage and creep. The use of larger sized coarse aggregates may be useful in limiting cement content, yet larger sized coarse aggregates may also decrease concrete strength by weakening the aggregate-cement paste bond. In many transportation structures, such as pavements, concrete strength is not critical, as dimensional stability, porosity, and durability play a more important role. It is possible, therefore, that larger sized coarse aggregates can reduce the cement content and improve these properties. Laboratory research is needed to determine if larger sized coarse aggregates can improve cement efficiency without reducing concrete strength.
