The hydration products of portland cement and water, a poorly-crystallized calcium-silicate-hydrate, calcium hydroxide, and sulfoaluminates, are responsible for the strength in portland cement concrete
Fly ash, a byproduct of coal-fired electric power production, is routinely used, for example, in the creation of portland cement concrete
Portland cement concrete
has three main components: small rocks ("coarse aggregate"), sand ("fine aggregate"), and a fine white powder called Portland cement.
The study concludes that 38 states are using RCA as an aggregate base, but just 11 are putting RCA back into Portland cement concrete
This project seeks to help overcome the barriers to widespread use of recycled materials as an aggregate by pursuing a research effort that focuses on evaluating potential aggregate materials other than reclaimed hot mix asphalt (HMA) and Portland cement concrete
Also included in the project will be the construction of approximately 53,000 linear feet of concrete barrier, 139,000 square yards of portland cement concrete
pavement, 309,000 square yards of 3-inch bonded concrete pavement overlay, 219,000 tons of asphalt concrete pavement, 6,000 linear feet of reinforced concrete drainage pipe and 799,000 pounds of reinforcing steel.

In portland cement concrete
, water has two functions: It hydrates cement particles to bind fine and coarse aggregate and acts as plasticizer during mix production and placement.
ICAR selected Forster for the award in recognition of his many years of national leadership in researching aggregates-related performance issues for portland cement concrete
The work consists of grading, surfacing and draining the roadways; furnishing and placing asphaltic concrete and Portland cement concrete
pavement; constructing retaining walls, concrete barriers, curb and gutter, storm drains and other incidental work.
