Embodiment Construction
[0014] High-strength manhole concrete, including the following components by weight: 360 parts of ordinary Portland cement, 75 parts of fly ash, 30 parts of modified asphalt, 72 parts of nano wollastonite powder, tetraisopropylbis(dioctyl Phosphite acyloxy) titanate 2.5 parts, styrene-acrylic emulsion 25 parts, straw ash 105 parts, carbide slag 36 parts, crushed pebbles 1100 parts, river sand 550 parts, water 145 parts, polycarboxylate high-performance water reducer 6 servings.
[0015] Wherein, the particle size of the crushed pebbles is 8mm; the particle size of the river sand is 5mm, and the mud content is less than 2%.
[0016] The modified asphalt is prepared by the following method: add 6% diatomaceous earth calcined powder to the base asphalt, heat up to 165, stir at a high speed of 1200rpm for 2min, then add 3% glass fiber, mix 1min, then add 4% mineral powder and mix together for 2min, then cool to room temperature.
[0017] The preparation method of hig...

Abstract
The invention discloses high-strength inspection well concrete which contains the following components in parts by weight: 350-400 parts of common silicate cement, 60-90 parts of coal ash, 20-30 parts of modified asphalt, 50-80 parts of nano wollastonite powder, 2-4 parts of tetraisopropyl bi(dioctylphosphiteacyloxy) titanate, 20-30 parts of styrene-acrylic emulsion, 100-200 parts of straw ash, 30-40 parts of carbide slag, 1,000-1,200 parts of broken pebble, 500-600 parts of river sand, 140-160 parts of water and 5-8 parts of polycarboxylic acid high performance water-reducing agent. Due to the formula adjustment and process improvement, the nano wollastonite powder is coated by the straw ash, so that various performances such as waterproof penetration, high-temperature resistance and high strength of the concrete can be improved. The produced concrete is high in strength, high in impact resistance, high in waterproof penetration property and high in durability.
Description
technical field [0001] The invention relates to concrete, in particular to a high-strength inspection well concrete and a preparation method thereof. Background technique [0002] Concrete is a combination of natural (or artificial) rock and sand with cementitious materials to form a hard whole. It has the advantages of easy molding, low energy consumption, good durability and low price, and can be made into various The advantage of this kind of load-bearing mechanism is that it is the most widely used building material in contemporary times and plays a very important role in the development of human society. At present, concrete still has the disadvantages of poor strength, high brittleness, large drying shrinkage, and easy cracking. Most of the inspection wells used in the existing urban sewage treatment systems are made of concrete, but there are problems such as toughness and low strength. Therefore, developing a high-strength manhole concrete to meet the needs of high...
