An attempt has been made through this study to find out a suitable mix proportion of desired strength by replacing sand with crusher dust in cement concrete, at the same time retaining its quality.
Whereas, a roller-compacted concrete pavement built to replace a failed pavement on a major route may require reaching 2,500 psi compressive strength and be opened for traffic within one or two days from placement. Different mixes of roller-compacted concrete can be designed to meet the different requirements of the two applications.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Reclaimed concrete material (RCM) is sometimes referred to as recycled concrete pavement (RCP), or crushed concrete. It consists of high-quality, well-graded aggregates (usually mineral aggregates), bonded by a hardened cementitious paste. The aggregates comprise approximately 60 to 75 percent of the total volume of concrete.

RCC refers to a stiff, zero-slump concrete mixture that is placed (typically with asphalt-type paving equipment) and then compacted with rollers. Background Like conventional ready mixed concrete, RCC has the same basic ingredients of cement, fine and coarse aggregates, and water. However, unlike conventional concrete, RCC is a drier material that

The National Concrete Pavement Techniology Center (CP Tech Center), Austin, Texas, and the Federal Highway Administration (FHWA) are developing a technology deployment plan that includes strategies for educating state DOTs and industry personnel on the CCA use in new concrete paving mixtures.
thermal stresses develop on the concrete structure, curing is not needed. However, because of their surface-to-volume ratio and exposure, pavements rarely are in this class of concrete. Significant damage to a concrete pavement can result when conditions exceed these critical limits and when curing practices are improperly applied.

Recycled Concrete Aggregates (RCAs) are a low cost alternative to natural aggregates produced from crushing demolished concrete. Typically only the coarse RCAs are used for new concrete because the fines have negative effects on the workability and strength of the new concrete. RCAa are assumed to lower the cost of the concrete pavement pavement.
