Gary Brenno of Cemstone's quality control department showed MnDOT test data revealing the effects of GGBF slag on heat of hydration and later strengths in concrete. Nelson had agreed that the 4000-psi strength specified for the pier footings and stems by designer Figg Engineering was to be reached at 56 instead of 28 days because loading wouldn't occur quickly.

The application of cement asphalt mortar (CAM) in modern high-speed railways has been gaining attention due to its combined merits between asphalt and cement hydration product characteristics. To promote sustainable development, it is promising to utilize by-products in the making of new CAM instead of using only cement. In this research, the cement content was partly replaced by fly ash or ...

The workability and durability of a type of sustainable concrete made with steel slag powder were investigated. The hydrated products of cement paste with ground granulated blast furnace slag (GGBFS) alone or with a combined admixture of GGBFS-steel slag powder were investigated by X-ray diffraction (XRD). Furthermore, the mechanism of chemically activated steel slag powder was also studied.

Effect of slag cement on the flowability of UHPC mixes (the measuring cone has a 100-mm bottom diameter; thus 100-mm spread indicates no spread at all). The air content of UHPC mixes was measured in the fresh state using the unit weight method and characterized in the hardened state using the ASTM C457 linear traverse method. As listed in Table 3, the total air content in the hardened concrete ...

Effect of Cement Content on Durability of Fly AshCarbide . The results show that when the optimal cement content is 150kg/m 3 and the fly ash —carbide slag content is 350kg/m 3, the impermeability, the frost resistance, the erosiveness resistance and the wear resistances of residue concrete are obviously improved, which can meet the pavement surface requirements of rural roads in the Three ...

Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,

Results showed the effect of slag on concrete transport properties. The effect of limestone filler was minimal either admixed solely or in conjunction with slag. On the other hand, blended cement appeared to be less effective on improving concrete transport properties. Compressive strength was less affected than transport properties by slag inclusion.
