Embodiment 1

[0031] 1. Pretreatment of sludge

[0032] After fully stirring the wet silt produced by river dredging and reclamation projects, soak it in 20% sodium hydroxide solution for 8 hours to remove harmful bacteria and microorganisms contained in the silt. Then pave the treated wet silt and place it in a sunny and well-ventilated open space for about a week. Manually pulverize the dried sludge and pass through a 5mm square hole sieve to remove impurities and irregular particles in the sludge. The dried sludge particles were put into a ball mill with a volume of 10 L and ball milled at a speed of 30 rpm for 20 minutes. The ground sludge particles were sealed and placed for 48 hours. The average size of the ground sludge particles was measured by a laser particle size analyzer to be 11.578 μm. Put the finely ground sludge particle powder into a 5L muffle furnace, heat up to 750-800°C at a rate of 5°C / min, heat treatment at this temperature for 4 hours, then cool the sludge particle p...

Abstract

The invention discloses an inorganic-polymer mud solidification mortar and a preparation method thereof. The preparation method comprises the following steps: subjecting heavy metal-containing mud produced in offshore engineering to physical-chemical treatment so as to obtain mud particles; then dissolving fly ash in a solution of soluble glass exciting agent, adding the treated mud and stone flour and carrying out mixing under stirring; and adding solid calcium oxide and carrying out stirring. The preparation method provided by the invention overcomes the disadvantage that a great amount of cement is needed in preparation of traditional cement mud solidification materials, reduces influence of production of greenhouse gases like CO2 and discharge of industrial dust in cement production to environment, makes full use of industrial waste like fly ash and waste stone flour for preparation of the mud solidification mortar and enables the industrial waste to be fully recycled and reused; through addition of solid calcium oxide, unwanted free water in the mixture is absorbed and the hydration reaction of an inorganic polymer is accelerated; and the inorganic-polymer mud solidification mortar has excellent early-stage mechanical properties.

Description

technical field [0001] The invention relates to an inorganic polymer sludge solidified mortar and a preparation method thereof, in particular to a method for preparing inorganic polymer sludge solidified mortar with good early performance by using fly ash, stone powder and solid calcium oxide. Background technique [0002] In recent decades, with the implementation of my country's "Belt and Road" project and the "Maritime Silk Road", the rapid development of my country's ports, waterways, offshore and marine engineering construction, the amount of silt cleaned up by various projects continues to increase every year , the amount of marine silt in 2000 alone reached 9518m 3 , After 2010, the amount of silt produced every year is still increasing exponentially. The traditional sludge treatment method is dumping, which takes up a lot of valuable cultivated land resources in our country and has high processing costs. More importantly, the silt produced in these marine projects c...
