Abstract
The present invention relates to a building material-masonry plaster. It is formed from flyash and auxiliary material. Said auxiliary material is made up by using plaster stone and calcium lime and adding proper quantity of water through curing process. Both of them can be used as finished product and can be separately packaged and stored, and when they are used, they are mixed and the small quantity of integration agent and yellow sand can be added to form the invented masonry plaster which can be used in the building site. Said invention is simple in production process, and their separate storage can ensure product quality and freshness.
Description
(1) technical field
The present invention relates to building material field, specifically a kind of masonry finishing mortar.
(2) background technology
Since portland-type cement was extensive use of, people mostly used gelling material and the wall guard material of cement as masonry.In order to satisfy the workability requirement in the actually operating, add a certain amount of lime putty or other softening agent usually.No matter be masonry mortar, or plastering mortar, the isostructure concrete is compared, belong to low strength grade, fine aggregate concrete, this shows, the mortar made from above-mentioned materials, just the low grade mortar that is mixed with cement of high index obviously exists the irrationality in the use.In addition, because the portland-type cement hydration rate is fast, the fully slaking of lime that partly overdoes after the wall plaster, crackle often occurs, plays (drum) bubble, even comes off.And another side still has the flyash of a big chunk power plant to be underutilized and to drain into storage ash field at present, has not only taken the soil, has also polluted environment.
(3) summary of the invention
The objective of the invention is to overcome existing build by laying bricks or stones, plastering mortar above shortcomings part, the abundant potential pozzolanic activity of applying powder coal ash, and carry out alkali-activator (this back warp is called compounding ingredient) and excite its active principle; Heat release energy when rationally utilizing the unslaked lime slaking adopts the proportioning of science, makes a kind of masonry finishing mortar of novelty.
By masonry finishing mortar proposed by the invention, it is mixed by flyash and compounding ingredient and forms, the consisting of of its compounding ingredient: plaster stone 8.5-23% (W/W), unslaked lime 92-77% (W/W), integrated agent trace.
Component and production method to masonry finishing mortar of the present invention is explained in detail below.
At first prepare II level flyash, to the former ash of power plant, except that fineness, all the other every indexs will be carried out physics and chemistry and be detected, and carry out levigate processing after meeting the requirements, and reach the above flyash of GB II level (containing the II level), the pack warehouse-in.
Carry out compounding ingredient processing.Elder generation is to the CaSO of gypsum
42H
2The CaO content of O content and unslaked lime detects, determine according to the above ratio to go into mill jointly after the proportioning, the ball milling fineness be 0.08 tail over≤10%.Plaster stone goes into to grind water content＜2%.On slaking storehouse (bin) top, vaporific tap water is sprayed in the compounding ingredient ingress, and the water yield makes unslaked lime slaking and heat release with CaSO by the 15-25% (W/W) of ball milling load behind the water spray
42H
2The O dehydration is decomposed into
Then to this compounding ingredient packing warehouse-in.
In use, with the II level flyash 70%-75% (W/W) that separately packs, compounding ingredient 25-30% (W/W), the mixed system of mixing, and, form masonry finishing mortar with the normal temperature adding when mixing system of micro-integrated agent.And then add and a certain proportion of yellow ground, form the building site and join mortar in fact, can use on the spot.
Masonry finishing mortar production technique of the present invention is simple.Owing to, dispatch from the factory in proportion with flyash and compounding ingredient packing separately, the use that matches at the construction field (site), the period of storage that has prolonged this product has guaranteed the freshness of compounding ingredient.In addition, owing to utilized flyash in a large number, the heat release energy when having brought into play the potential pozzolanic activity of flyash and unslaked lime slaking has to a great extent reduced the cost of product, alleviates the environmental pollution that flyash causes.
(4) description of drawings
Accompanying drawing 1 is inhaled (putting) hot temperature---time curve for gypsum powder, full calcium lime powder, compounding ingredient maturing process in the storehouse in the production technique of the present invention.
Among the figure, 1. curve is gypsum powder (0.08 tails over 6%) heat absorption dehydration temperaturre---time changing curve; 2. curve adds water cure exothermic temperature---time changing curve for full calcium lime powder (0.08 tails over 4%); 3. curve is that the compounding ingredient that gypsum powder (sample together 1.) and calcium lime powder (sample together 2.) match by a certain percentage adds water cure temperature---time changing curve.
Three road curves from accompanying drawing are as can be seen: the product of the hot temperature value of three kinds of suctions (putting) (getting the mean value of per 5 minutes one values) the same time of equivalent weight (unit is for dividing) is:
2.S
Tt＞
3.S
Tt＞
1.S
Tt(time period only got 85 minutes)
The explanation of obtaining a result thus: the calcium lime powder slaking heat release in gypsum powder, the calcium lime powder mixture is enough to make plaster stone (CaSO
42H
2O) dehydration is semi-hydrated gypsum
Through test, with curve 2. slaking thing and curve 3. the slaking thing simultaneously, make t time of coagulation of test block (process) with environment
3.＜t
2.Hardened intensity P in the air
3.＞P
2., illustrate that the interior semi-hydrated gypsum of mixture is reduced into hard dihydrate gypsum its intensity is increased.
(5) embodiment
[embodiment 1] prepares masonry finishing mortar in following ratio:
II level flyash 75% (W/W)
Compounding ingredient 25% (W/W) (wherein unslaked lime 84%, plaster stone 16%, W/W)
Integrated agent is about 1 ‰ of a glue sand test water consumption.
Product glue sand is tested detection, its result such as following table by operative norm GB1345, GB1346, GB2419, GB177, GB13 (J) 11-97, GB1596-91 then:
| Time (my god) | Resistance to compression mean value (Mpa) | Anti-folding mean value (Mpa) | Stability |
| ????14 | ????5.5 | ????1.85 | Qualified |
| ????28 | ????10.5 | ????3.03 | Qualified |
| ????60 | ????20.5 | ????4.4 | Qualified |
| ????90 | ????26.8 | ????5.4 | Qualified |
The real mortar test result of joining in [embodiment 2] building site:
By last example preparation masonry finishing mortar: yellow ground (water content 4%)=1: 3.65 (W/W).
Making 28 days average strengths of mortar specimen is 3.6Mpa, unit weight 1.67-1.78g/cm
