Abstract
A manufacturing method of pre-mixing mortar is a convenient and fast process which can markedly reduce the cost of the pre-mixing mortar and energy consumption in the manufacture and application of the pre-mixing mortar. The method comprises the steps as below: 1. preparing a cementing material, being formed by compounding general purpose portland cement, mortar mixture and mineral admixture with the proportionality range of 100:0.01-10:5-100, special for the compound pre-mixing mortar, 2. preparing naturally dried sand in the open air with the range of the water ratio below 8%; 3. respectively putting the special cementing material and the sand in a special storage tank, and before preparing the mortar, avoiding contacting the special cementing material with the sand; and 4. transporting the special cementing material, the sand and water into a stirrer for fully and evenly stirring pro rata.
Description
Technical field
The present invention is a kind of in the production and application of premixing mortar, is guaranteeing that the premixing mortar fundamental property satisfies the production technique that can significantly reduce the premixing mortar production cost when current standards requires, and belongs to the field of premixing mortar technology.
Background technology
Traditional production technique be raw material (cement, sand, additive etc.) through processing (screening of sand and oven dry), storage tank stores, metering, stirring, metering packing or storage tank, transportation (packed or bulk shipment) to the building site, building-site add water stir mortar product.Main process is all finished in specialized premixing mortar factory, stirs into mortar product to building site Jia Shui and is delivered for use.Its subject matter is that cost is higher.The reason that cost stirs far above the scene is: (1) facility investment is bigger, and home equipment generally needs 600-700 ten thousand Renminbi, and import equipment then needs 1200-1,500 ten thousand Renminbi; (2) sand oven dry is about cost doubles after the oven dry of sand per ton; (3) packed mortar also needs 10 yuan every bag packing bag expense.
This patent then is that the premixing mortar production process is decomposed into three parts: (1) gelling material batch production is produced; (2) sand pre-treatment (screening and suitably dry); (3) mix the finished product mortar according to the on-the-spot sealing of mortar design requirements machinery.By said process cost is reduced to about 50% of professional premixing mortar factory mortar cost.
Summary of the invention
Technical problem: the objective of the invention is, cost more than problems such as height, a kind of production method of premixing mortar is provided at operation in the preparation process of premixing mortar.The premixing mortar that utilizes this technology and equipment to prepare can reduce facility investment and premixing mortar cost significantly under the condition that satisfies the current standards standard.
Technical scheme: the method steps of premixing mortar production of the present invention is:
Step 1: prepare compound premixing mortar special adhesive gel material, this special adhesive gel material is composited by general purpose portland cement, mortar additive and mineral admixture, its proportional range is: general purpose portland cement: mortar additive: mineral admixture=100:0.01～10:5～100, and concrete ratio is determined by test according to mortar performance, cement performance, admixture performance and mineral admixture performance;
Step 2: the sand of preparation natural air drying, its water ratio scope is below 8%, other performance index of sand meet existing building sand standard;
Step 3: adopt special-purpose logistics storage facilities that special adhesive gel material and described sand are transported to the building site respectively and be positioned in the special-purpose storage tank, perhaps adopt special-purpose storage tank, special adhesive gel material and sand are packed in the separation of storage tank, and before the preparation mortar, the special adhesive gel material does not contact with sand;
Step 4: when needs prepare mortar, adopt the situ metrology whipping device, in proportion special adhesive gel material, Sha Heshui in the storage tank are sent in the agitator and stir, the ratio of the two is: special adhesive gel material: sand: water=1:1～6:0.3～1, determine concrete ratio according to the performance and the mortar design requirements of special adhesive gel material performance, sand.
Beneficial effect: advantage of the present invention comprises:
(1) traditional premixing mortar factory is built in not sole investment, has saved the drying plant of sand., set up the sand field in communications and transportation easily along the river or the limit, canal, the sand of this sand field adopts natural air drying, make it water ratio≤10% (with this understanding, sand can be transported to the silo top by lift, is delivered to then in the premixing mortar silo), qualified sand is transported to the building site.
The shop equipment of (2) production special adhesive gel material is simple, only needs metering, mixing and storage facilities to get final product, and also can utilize the device fabrication at existing cement or grinding station.This patent can use (i) general purpose portland cement+mineral admixture+additive about gelling material; (ii) can use alkali to excite gelling material+additive; The (iii) gelling material that allows of other any current standards and design.Its production technique can be utilized existing cement grinding station equipment.Thus can the minimum qualified gelling material of alternative costs, as adopting gelling material (i), can guarantee that then the mortar quality satisfies under the condition that current standards requires, and mixes mineral admixture to greatest extent, thereby reduces material cost.
(3) easy and simple to handle, meet and forbid the on-the-spot policy requirements that stirs mortar.When premixing mortar is used in the construction site, storage tank is transported to the building site with special-purpose carrier, then sand, special adhesive gel material are transported to the building site; Load onto agitator in silo bottom, utilize the circuit and the electronics metering outfit control valve that have been equipped with, a certain proportion of sand, special adhesive gel material and water are transported to transport out after stirring in the agitator are mortar product.This patent can utilize existing containerization logistics equipment to transport mortar to building site and store about scene sealing mechanical stirring preparation mortar product, mixes system by special-purpose agitator then; Also can utilize general closed mortar mixer scene to mix system.
(4) because above-mentioned (1)-(3), this technology has characteristics, particularly production cost such as less investment, production cost is low, quality control is more effective can reduce to present 50%.
