▎ 摘  要

NOVELTY - Ultra-high toughness alkali excitation spraying concrete comprises 400-600 pts. wt. cement, 100-200 pts. wt. slag, 90-180 pts. wt. zeolite powder, 20-60 pts. wt. sodium hydroxide solution, 25-45 pts. wt. sodium silicate, 300-600 pts. wt. nickel slag sand, 3-6 pts. wt. thickening agent, 10-50 pts. wt. modified polyacrylonitrile fiber, 30-80 pts. wt. steel fiber, 5-12 pts. wt. naphthalene water reducer, and 250-350 pts. wt. water. USE - The alkali excitation spraying concrete is useful in slope, mine, tunnel, and underground engineering. ADVANTAGE - The alkali excitation spraying concrete has a lower rebound rate, high compression strength, compactness and crack resistance. The method optimizes and improves the performance of the injection concrete; and has simple operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of high-strength concrete.
