cementitious material

cementitious material

[¦sē‚men¦tish·əs mə′tir·ē·əl]
(materials)
Any of various building materials which may be mixed with a liquid, such as water, to form a plastic paste, and to which an aggregate may be added; includes cements, limes, and mortar.

cementitious material

A material (with or without an aggregate) that provides plasticity, cohesive, and adhesive properties when it is mixed with water—properties that are necessary for its placement and formation into a rigid mass.

There is no need to specify minimum cementitious material contents in concrete mixes, as overspecification increases costs and a project's carbon footprint, while potentially compromising performance, say Karthik H.
Civil engineers who specialize in concrete and composites present 50 papers on such topics as using heat pretreatment to reduce the explosive spalling of high performance concrete, mechanical properties and resistance to water ingress of cement concrete made with non-cyclic alkanes, a comparative investigation of some properties related to the durability of cement concretes containing different fly ashes, mechanical and thermal properties of moderate-strength concrete with ceramic powder used as supplementary cementitious material, and mechanical and thermal properties of composites containing waste coir pith.
Dispersion of nanotubes in cementitious material, however, is a major issue because they do not disperse easily through the cement paste as it flows into place.
To meet this constraint and limit the use of natural resources in its concrete production, the CEMEX team developed a formula using components with low energy consumption; particularly, a supplementary cementitious material was used as a binder.
They immediately began the process of lowering cementitious material content and dosing concrete mixes with carbon dioxide (C[O.
Today, concrete or cementitious-based PFP materials are widely used in the hydrocarbon process and related industries to manage risks associated with pool fires, he explains, Installation of lightweight cementitious material often includes welded or galvanised steel mesh systems, all of which add to cost, installation time whilst extending the shutdown period.

Citing the company's tradition of introducing sustainable concepts into its products and manufacturing processes, Superior Block President Connie Cincotta notes: "We've been offering products made with a high percentage of recycled and supplementary cementitious material for years.
INTENT & SCOPE OF WORK The Contractor shall construct Full Depth Reclamation (FDR), including injection of asphalt emulsion and cementitious material to a depth of approximately twelve (12) inches, and place a two (2) inch asphalt overly along S.
They were additionally challenged to develop a mixture that demonstrated cementitious efficiency--maintaining the overall concrete performance with the lowest amount of cementitious material.
Concrete shall be designed to achieve a minimum flexural strength of 4300 kPA at 28 days, using aminimum of 300kg of cementitious material per cubic meter.
The proposed union triggered what was likely one of the most complex investigations of cementitious material production and distribution markets in FTC history.
