Problems solved by technology

Finally, the aerobic sulfur oxidizing bacteria, namely Tiobacillus Tiooxidance, is greatly increased to produce sulfuric acid. Since this sulfuric acid is strongly acidic, it initiates the neutralization reaction of the concrete in the dry-mixed mortar and begins to melt, resulting in a decrease in the strength of the dry-mixed mortar.
In addition, when sulfate ions move to the inside to form supersaturation, monosulfate will be transformed into ettringite, which will roughen the hardened concrete and cause cracks, and promote the intrusion of corrosive substances to shorten the service life. , and then lead to many problems such as indoor environment pollution due to the invasion of harmful microorganisms

Embodiment 1

[0027] The specification (type) of dry-mixed mortar is mortar for the ground, and the matching standard is to design the ratio of dry sand and cement to 2.6:1 weight percent. The above cement is mixed with cement when the entire cement is regarded as 100 weight percent. 68% by weight, 14% by weight of fly ash, and 18% by weight of expansion agent.

[0028] That is, 720kg of dry sand, 190kg of cement, 40kg of fly ash, and 50kg of expansion agent are mixed into each ton (TON) of dry-mixed mortar, and then 0.02kg of thickener is mixed as an additive, and beneficial microorganisms are added after replacing water. That is, the actual amount of water used is 112-157 kg minus the mixed amount of beneficial microorganisms (13-18 kg).

[0029] The total amount of water used in each ton (TON) of dry-mixed mortar is 125-175kg, and then mixed with 13-18kg of beneficial microorganisms, and poured after mixing with each other. That is, the actual amount of water used is 112-157 kg minus th...

Embodiment 2

[0036] The specification (type) of the dry-mixed mortar is ordinary plastering mortar, and the matching standard is to design the ratio of dry sand and cementing material to 2.6:1. The above-mentioned cementing material is regarded as 100% by weight of the entire cementing material It is formed by mixing 93% by weight of cement and 7% by weight of fly ash.

[0037] That is, 720kg of dry sand, 260kg of cement, and 20.0kg of fly ash are mixed into each ton (TON) of dry-mixed mortar, and then 0.133kg of thickener is mixed as an admixture, and finally water and the total amount of water are added before pouring on site 10% of beneficial microorganisms.

[0038] The total amount of water used in each ton (TON) of dry-mixed mortar is 125-175kg, and the amount of mixed beneficial microorganisms is 13-18kg, which are poured after being mixed with each other. At this time, the amount of water used is 112-157 kg minus the total amount of mixed beneficial microorganisms.

[0039] Table...

Embodiment 3

[0045] The specification (type) of dry-mixed mortar is to choose the mortar for spraying, and the matching standard is to design the ratio of dry sand material and cementing material to 1.5:1, and the cementing material is to mix 63 weight percent of cement when the whole cementing material is regarded as 100 weight percent , 32% by weight of fly ash, 5% by weight of expansion agent, and 3.7% by weight of admixture. That is, the cement is a mixture of cement, fly ash, expansion agent, and admixture.

[0046] Mix 600kg of dry sand, 252kg of cement, 128kg of fly ash, 20kg of expansion agent, and 14.8kg of admixture in each ton (TON) of dry-mixed mortar, and then add water and 10% by weight of the total 100% by weight of water on site of beneficial microorganisms.

[0047] The total amount of water used in each ton (TON) of dry-mixed mortar is 175-225kg, and then the water is replaced to mix 18-23kg of beneficial microorganisms. That is, the actual amount of water used is 157-2...

Abstract

The invention provides an environment friendly antifungal dry mortar. The environment friendly antifungal dry mortar comprises a mixture (a) having 60-80 weight percent of mixed sand and 20-40 weight percent of cementing agent based on the total 100 weight percent, beneficial microorganisms (b) and water (c). The beneficial microorganisms (b) comprise a mixture consisting of more than one of the photosynthetic bacterium, aerobe, physiologically active substance, yeasts and lactobacillus. The water is prepared by replacing 1-20 weight percent of water based on the total 100 weight percent. The invention has functions of self-disinfection, antibiosis and deodorization, and is capable of removing bacterium, mould and so on, therefore greatly improving living environment, decomposing substances that induce syndrome of new residence such as volatile organic compounds (VOC), formaldehyde (HCHO) and toluene, as well as effectively deodorizing.

Description

technical field [0001] The invention relates to an environment-friendly antibacterial dry-mixed mortar (Dry Ready Mixed Cement Mortar). Background technique [0002] Usually, dry-mixed mortar (Dry Ready Mixed Cement Mortar) manufacturing plants use a variety of matching methods to mix raw materials and auxiliary materials, namely dry sand and cement (mixture with concrete as the main component) at a ratio of 2.5-4:1. Mixing ratio After mixing, it is delivered to the construction site in a dry state by a truck (BULK TRUCK), and it is mixed with 12-22% by weight of water before pouring. The quality inspection of the product is carried out at the time of delivery, and the inspection standard should comply with the Korean Industrial Standards (KS, Korean IndustrialStandards). The quality inspection method is that its water retention, air content, and compressive strength should meet the inspection standards. Specifically, the water retention (Wt%) should be 65-75%, the air cont...
