70 ConcreteInternational were used to improve the fluidity of stiff mixtures without altering the water-to-cementitious material ratio (w/cm). As it is possible to realize both the objectives simultaneously, now superplasticizing admixtures are used throughout the world for the
Social and environmental benefits of precast concrete technology
free download
Contractors have long recog nized that conventional in situ construction in large cities has resulted in excessive labor costs due to time lost in transporting workers to and from the project site through con gested vehicular traffic. This loss of time is further compounded by
VERDiCT: viscosity enhancers reducing diffusion in concrete technology
free download
Reinforced concrete structures are susceptible to attack by elements of the environment including chloride and sulfate ions. Past attempts at increasing service life have generally focused on limiting the ingress of these deleterious elements by producing less permeable
Applying concrete technology to abrasion resistance
free download
The many factors that contribute towards abrasion resistance in concrete (with special reference to concrete pavers) are considered. These include the various raw materials, their specific characteristics, and some manufacturing processes that contribute to abrasion
Recyclable materials in concrete technology : sustainability and durability
free download
A judicious use of natural resources, achieved by the use of by-products and recyclable materials, and a lower environmental impact, achieved through reduced carbon dioxide emission and reduced natural aggregate extraction from quarries; represent two main
