Abstract

The invention discloses early strength concrete for power line mounting, and belongs to the technical field of concrete. The early strength concrete comprises the following raw materials in parts by weight: 80-100 parts of sulfate aluminium cement, 45-50 parts of steel fiber, 30-40 parts of glass fiber, 22-25 parts of ceramic hollow beads, 14-16 parts of glass-ceramic powder, 20-25 parts of quartz powder, 250-270 parts of aggregate, 8-10 parts of zinc oxide, 3-7 parts of molybdenum disulfide, 1-3 parts of triisopropanolamine, 1-2 parts of lithium carbonate, 2-4 parts of aluminum sulfate, 0.5-1 part of sodium hydroxide, 7-9 parts of a water reducing agent, 1-2 parts of a defoaming agent, 2-4 parts of an anti-freezing agent and 30-50 parts of water. The invention further discloses a preparation method of the early strength concrete for power line mounting. The early strength concrete is relatively good in early strength, excellent in high temperature resistance, excellent in anti-freezing property and short in maintenance time.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an early-strength concrete for installing power lines and a preparation method thereof. Background technique [0002] At present, in order to solve the problems of low early strength and long curing time of cast-in-place concrete in the foundation construction process, people usually use high-strength Portland cement concrete instead of ordinary-strength Portland cement concrete or use high-strength silicate Salt cement concrete is used to replace ordinary strength Portland cement concrete and at the same time, early strength agent is added to improve early strength. [0003] By using high-strength Portland cement concrete instead of ordinary-strength Portland cement concrete, the early strength of high-strength concrete is higher than that of ordinary-strength concrete. The disadvantage of this method is that the later strength is too high, and its strength is not fully utilize...
