Embodiment 1

[0023] This embodiment is an example of the preparation method of the bagasse ash concrete of the present invention. The components and their corresponding parts by mass are shown in Table 1. The bagasse ash in this embodiment is used to replace part of the cement in an amount of 10%. Prepare bagasse ash concrete according to above-mentioned proportioning, comprise the steps:

[0024] Step 1: Calcining the bagasse ash at a high temperature of 650° C. for 1 hour, and cooling naturally. Add 0.05% triisopropanolamine (TIPA) to the cooled bagasse ash raw material, grind it in a ball mill until the sieve residue of 45 μm is less than 10%, and the specific surface area of ​​the bagasse ash prepared at this time is 943m 2 / kg.

[0025] Step 2: Put the bagasse ash and cement pretreated in corresponding parts by mass into a mixer and stir for 3 minutes to obtain a dry mix mixture, and further mix and stir with gravel, sand, water, and water reducing agent for 3 minutes to obtain a ba...

Embodiment 2

[0029] This embodiment is another example of the preparation method of bagasse ash concrete according to the present invention. The components and their corresponding parts by mass are shown in Table 1. The specific preparation method is basically similar to Example 1, except that this Example of bagasse ash to replace part of the cement with a dosage of 15%.

Embodiment 3

[0031] This example is another example of the preparation method of bagasse ash concrete according to the present invention. The difference is that the components and their corresponding parts by mass are shown in Table 1, and the bagasse ash is calcined at a high temperature of 400 ° C. 1h, natural cooling. Add 0.05% triisopropanolamine (TIPA) to the cooled bagasse ash raw material, grind it in a ball mill until the sieve residue of 45 μm is less than 5%, and the specific surface area of ​​the bagasse ash prepared at this time is 1250m 2 / kg, while the curing method adopts thermal curing curing treatment, and the bagasse ash in this example replaces part of the cement with a dosage of 10%.

Abstract

The invention discloses bagasse ash concrete and a preparation method thereof. The preparation method comprises the following steps: pretreating bagasse ash discharged from a furnace of a sugar refinery so that the activity of the bagasse ash is improved; taking the pretreated bagasse ash as a raw material for preparing concrete, mixing and stirring with sand, stone, water, cement and a water reducing agent, pouring and vibrating to prepare a bagasse ash concrete product, and further curing by one of standard curing and thermal curing. The prepared bagasse ash concrete has high structural strength and durability. Compared with traditional concrete, the bagasse ash concrete has the advantages that on the premise that the performance is improved, the bagasse ash can be fully reused, the resource consumption is reduced, and economic and environment-friendly production is facilitated.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of bagasse ash concrete. Background technique [0002] As a hard artificial stone, concrete is widely used in various projects because of its excellent physical and mechanical properties. It is currently the most used building material in the world. As an important component of concrete, cement has the disadvantages of high energy consumption, high pollution, and high cost. To a certain extent, it aggravates the greenhouse effect and causes harm to the environment. In recent years, green and environmentally friendly building materials have attracted a lot of attention. Continuous research has shown that agricultural by-products such as bagasse ash not only have huge yields, but also can be used as mineral admixtures to improve various properties of concrete. [0003] Bagasse ash is taken from the high-temperature furnace of the sugar factory, which is the a...
