High Strength Concrete

Water-Reducing Agents and Superplasticizers. Common admixtures that improve fluidity of concrete mixes are often used in high strength concrete. These admixtures make possible the incorporation of siUca fume while maintaining necessary workabiUty. Three principal types of... [Pg.290]

Silica powder has been studied as a stabilizer for oil well cement at high temperatures [1895]. Tests indicated that silica powder can improve the stability and pressure resistance strength of cement. The manufacture of very-high-strength concrete (after 28 days the compressive strength is greater than... [Pg.132]

The Hibernia offshore concrete platform on the Grand Banks off the coast of Newfoundland, Canada, is a 111 m structure and required about 165 000 m of superplaticized high-strength concrete. The typical mixture proportions and the properties of the concrete used for the skirt elements of the structure are shown in Table 7.18 [70]. The precast skirts are a series of reinforced concrete elements which were joined together to form continuous walls to support the base slab of the structure [69]. [Pg.462]

Concretes that were previously (late 1970s) known as high-strength concretes are now referred to as high-performance concretes. This is because high-strength concrete embodies enhanced performance in other areas such as durability and abrasion resistance. Superplasticizers are essential ingredients in such concretes... [Pg.348]
