    摘要: A cement composition for a self-levelling concrete, includes a mixture of rheology-modifying additives, the combination of at least a first agent for substantially increasing the shear threshold of the concrete in the fluid state, selected from a natural polysaccharide ether, a hydroxyalkyl guar ether, a hydroxyethylcellulose or a hydroxypropyl guar, which are hydrophobically modified with the introduction of hydrophobic side grafts, and at least a second viscosity-increasing agent for substantially increasing the viscosity of the concrete in the fluid state, selected from a non-hydrophobically-modified hydroxyalkylcellulose having a degree of polymerization between approximately 500 and approximately 4500 and a viscosity of less than 50 PA·s in aqueous solution at 2 wt.-% and a poly (ethylene oxide), in order to limit or prevent the dynamic segregation of granulates in the concrete during the implementation thereof. The use of such a composition can replace the presence of a filler in the concrete, in particular a self-levelling concrete, without diminishing the performance concerning the spreading thereof, the sieve stability, the bleeding and the dynamic segregation relative to a concrete containing a filler, in particular a concrete having the same water/cement ratio.

    摘要: The invention includes a method of making and using a flowable thermal backfill. The flowable thermal backfill has a low thermal resistivity, useful for filling trenches containing electrical cables and other lines that generate heat. The method includes process steps of blending ingredients of stone, sand and fly ash, making a flowable thermal fill by mixing the blended stone, sand and fly ash with Portland cement and water, and pouring the flowable thermal fill in an excavation containing heat generating lines, immediately after mixing the flowable thermal backfill.
