example 1

[0018] Select phosphate rock slag and place it in a ball mill tank. After ball milling at 200r / min for 3 hours, pass through a 200-mesh sieve to obtain a ball-milled powder. Take moderate saline-alkali soil and grind it through a 100-mesh sieve to obtain a ground powder. The mass ratio is 1:10 , stir and mix the grinding powder with deionized water and let it stand for 6 hours, then centrifuge at 1500r / min and collect the supernatant to obtain the matrix liquid, and weigh 45 parts of the matrix liquid and 45 parts of water respectively in parts by weight , 2 parts of potassium nitrate, 3 parts of magnesium sulfate, and 1 part of calcium nitrate were stirred and mixed and dispersed ultrasonically for 10 minutes to obtain a nutrient solution; in parts by weight, 55 parts of ball mill powder, 10 parts of river sand, 25 parts of sawdust and 10 parts of sawdust were weighed respectively. Place the aluminum slag in a ball mill tank, and pass through a 100-mesh sieve to obtain the cul...

[0020] Select phosphate rock slag and place it in a ball mill tank. After ball milling at 250r / min for 4 hours, pass through a 200-mesh sieve to obtain a ball-milled powder. Take moderate saline-alkali soil and grind it through a 100-mesh sieve to obtain a ground powder. The mass ratio is 1:10 , stir and mix the grinding powder with deionized water and let it stand for 7 hours, then centrifuge at 1750r / min and collect the supernatant to obtain the matrix liquid. In parts by weight, weigh 47 parts of the matrix liquid and 47 parts of water respectively , 2 parts of potassium nitrate, 4 parts of magnesium sulfate, and 2 parts of calcium nitrate were stirred and mixed and ultrasonically dispersed for 12 minutes to obtain a nutrient solution; in parts by weight, 57 parts of ball mill powder, 12 parts of river sand, 27 parts of sawdust and 12 parts were weighed respectively. Place the aluminum slag in a ball mill tank, and pass through a 100-mesh sieve to obtain the culture substrat...

[0022]Select phosphate rock slag and place it in a ball mill tank. After ball milling at 300r / min for 5 hours, pass through a 200-mesh sieve to obtain a ball-milled powder. Take moderately saline-alkali soil and grind it through a 100-mesh sieve to obtain a ground powder. The mass ratio is 1:10 , stir and mix the ground powder with deionized water and let it stand for 8 hours, then centrifuge at 2000r / min and collect the supernatant to obtain the matrix liquid. In parts by weight, weigh 50 parts of the matrix liquid and 50 parts of water respectively , 3 parts of potassium nitrate, 5 parts of magnesium sulfate, and 2 parts of calcium nitrate were stirred and mixed and ultrasonically dispersed for 15 minutes to obtain a nutrient solution; Place the aluminum slag in a ball mill tank, and pass through a 100-mesh sieve to obtain the culture substrate; take the vigorously growing bushes of Amarina, Salicornia, and Suaeda salsa in October, collect seeds with better maturity, and rais...

Abstract

The invention relates to a method for preparing quick-hardening and early-strength phosphorus-slag-base cementitious materials, and belongs to the technical field of cementitious materials. The methodhas the advantages that phosphate slag is ground by means of ball-milling and is used as a cultivation medium for cultivating crops, the crops are cultivated on the surface of the cultivation medium,phosphorus inside the cultivation medium can be absorbed and can be completely utilized, and accordingly the content of phosphorus pentoxide inside the phosphate slag can be effectively reduced; surface structures of the phosphate slag can be effectively improved under the permeation and loading actions of the roots of the crops, the specific surface areas of the phosphate slag can be enlarged, and the structural performance of the quick-hardening and early-strength phosphorus-slag-base cementitious materials can be improved; leach liquor from saline-alkali soil is used as base solution of nutrient solution, plants such as salicornia europaea are effectively irrigated, phosphorus can be removed by the aid of growth and absorption actions of the plants, the quick-hardening and early-strength phosphorus-slag-base cementitious materials prepared from the phosphate slag are excited and modified by the leach liquor from the saline-alkali soil, and accordingly the dispersion and solubilityof the phosphate slag can be promoted; aluminum ore slag is added into the cultivation medium, accordingly, the contents of aluminum oxide materials in composite materials can be increased, and the quick-hardening and early-strength phosphorus-slag-base cementitious materials prepared by the aid of the method are excellent in quick-hardening and early-strength performance.

Description

technical field [0001] The invention relates to a preparation method of a fast-hardening and early-strength phosphorus slag-based cementitious material, belonging to the technical field of cementitious materials. Background technique [0002] Concrete is the most widely used and most common building material in engineering in the world today. Because of its easy-to-obtain raw materials, low cost, easy operation, and good durability, it is widely used in industrial and civil buildings, as well as construction projects such as transportation, water conservancy, and ocean. my country's infrastructure construction has experienced decades of peak construction, and my country will still build a large number of infrastructure in a long period of time in the future. With the development of economy and society, more and more infrastructure buildings need to be repaired and reinforced due to inadequate management, especially capital and technical constraints in design and constructio...
