33èmes rencontres de l’augc, isabtp/uppa, anglet, 27 au 29 mai 2015 2 1. introduction self-compacting concrete (scc), a new kind of high performance concrete (hpc) with excellent deformability and segregation resistance, was first developed in japan in 1986..efectos del curado en las propiedades de mezclas …,a pesar de que las propiedades mecánicas y la resistencia a la carbonatación de mezclas de concreto adicionadas con ggbs son bien conocidas, su resistencia a la carbonatación se encuentra aún en debate (sulapa et al, 2003; jia et al, 2012), adicionalmente, se ha sugerido que el efecto del tipo y calidad del curado son factores determinantes.new continuous concrete pour ... - hanson uk,we’ve helped set a new record for the largest continuous concrete pour in england at edf energy’s hinkley point c (hpc) new nuclear power station in somerset.we supplied the raw materials for the concrete to main civils contractor bylor, which operates the on-site concrete production plant.the 9,000 cubic metre, five-day, pour was to construct the last of five reinforced concrete segments
abstract the use of high performance concrete (hpc) focuses primarily on the durability rather than the strength. it is a sustainable and environmentally friendly material. the report discusses water impermeability on the hpc specimen containing silica fume. a concrete is considered good if it is less permeable and less porous. a test is conducted on 6 specimens to study the behavior for water.effect of alccofine on strength characteristics of,the major characteristics of high performance concrete. hpc is a concrete in which certain characteristics are developed for particular application and environment. durability is optional under the aci definition and this has led to a number of hpc structures, which should theoretically have.cracked silo at under-construction uk nuclear plant,the 115-foot (35-meter) tower buckled at around 7:30 am local time on wednesday. although initial reports were of an explosion, the smoke was in fact a cloud of ground granulated blast furnace slag (ggbs), which was being used to reinforce the concrete, according to a spokesperson with electricite de france (edf).
this paper analyzed the eco-efficiency of concretes (water/cement ratio = 0.50; cement content = 350 kg / m 3, and slump = 7 cm) with blended cement containing 25% by weight calcined pozzolan obtained from a low-grade kaolin (hkc) and an illitic shale (hic) compared with ordinary portland cement concrete (hpc).the fresh, mechanical, and transport properties of these concretes.strength and durability study on concrete with ggbs and,the optimum percentage levels of 7.5% ggbs and 0.3% glass fibre replacement to the weight of the cement is taken with the hpc m75 mix ratio of 1:1.03:1.973:0.26 which gave the better results. the compressive strength of 76.96 n/mm2 is achieved in the hpc mix due to the presence of ggbs which exhibits more filler effect..high energy milling (hem) of mexican minerals to produce,in order to produce high performance concrete (hpc), fine mexican mineral aggregates were characterized using chemical, physical and mineralogical procedures. used materials included fly-ash, micro silica, silica fume, and coarse, fine and refined ground granulated blast furnace slag (ggbs), which were then dosed with composite portland cement (cpc) in three forms: (1) commercially as-received
high performance concrete (hpc) has received increased attention in the development of infrastructure viz., buildings, industrial structures, hydraulic structures, bridges and highways etc. leading to utilization of large quantity of concrete. this paper presents a comprehensive coverage of high performance concrete developments in civil engineering field..a survey of high performance concrete developments in,high performance concrete (hpc) has received increased attention in the development of infrastructure viz., buildings, industrial structures, hydraulic structures, bridges and highways etc. leading to utilization of large quantity of concrete. this paper presents a comprehensive coverage of high performance concrete developments in civil engineering field..non-linear finite element analysis of ggbs & crf based,focuses on the mechanical properties of m60 hpc with partial replacement of cement by ground granulated blast furnace slag (ggbs) and fine aggregate by robo-sand (crusher dust) with the addition of super plasticizer. it is observed that the maximum compressive strength achieved in m60 grade of concrete is 65.3 mpa with 40% replacement of cement by
mechanical properties of m60 hpc concrete with the partial replacement of the cement by ggbs & fine aggregate by robosand (crusher dust) along with usage of superplasticizer in their work. the material utilized by them are as follows zuari cement which confirms to code were utilized in.development of a new in situ test method to measure the,hpc mixes contained scms, including microsilica (ms), pulversised fuel ash (pfa) and ground granulated blast-furnace slag (ggbs). cem-i cement confirming to bs-en 197  was used where applicable. pfa was obtained from kilroot power station in northern ireland, uk, with its properties conforming to bs-en 450 .
