Abstract
The invention discloses a kind of structure demolition remove special stemming and preparation method it is characterised in that：Its raw material includes water, sand and cement, and water, sand and cement are according to weight ratio (1 1.2):(2‑‑2.5):The ratio mixing of (1.2 1.5), three's mix homogeneously；Solve relatively costly, the constructing operation inconvenience that prior art adopts loess stemming to exist, blocking effect is bad, the technical problem such as easy punching.
Description
Technical field
The invention belongs to structure demolition projects field, more particularly, to a kind of structure demolition remove special stemming and
Preparation method.
Background technology
Domestic high-lager building is removed and is adopted blasting demolishing method more at present, during structure demolition Demolition Construction,
The blocking quality of blasthole successfully plays vital effect to whole engineering explosion effect and explosion, and current structure demolition is torn open
To be blocked using traditional loess stemming except blasthole is many, loess stemming is to buy from the producer of professional production stemming, using loess
Stemming blocking has a disadvantage that（1）It is relatively costly,（2）Constructing operation is inconvenient,（3）Blocking effect is bad, easy punching.
Content of the invention
The technical problem to be solved in the present invention：A kind of structure demolition is provided to remove special stemming and preparation method, to solve
Certainly prior art adopts relatively costly, the constructing operation inconvenience that loess stemming exists, and blocking effect is bad, the skill such as easy punching
Art problem.
Technical solution of the present invention：
Special stemming and preparation method are removed in a kind of structure demolition, and its raw material includes water, sand and cement, water, sand and water
Mud is according to weight ratio (1--1.2):(2--2.5):(1.2--1.5) ratio mixing, three's mix homogeneously.
Sand is the middle sand in 0.35-0.5mm for the particle diameter.
Cement is portland cement.
Beneficial effects of the present invention：
The stemming raw material of the present invention is easy to get, and cost is relatively low, simple to operation, and practicality and high efficiency is respond well, is particularly suitable for building
Thing blasting and dismantling engineering；Solve relatively costly, the constructing operation inconvenience that prior art adopts loess stemming to exist, blocking effect
Really bad, the technical problem such as easy punching.
Specific embodiment
Special stemming and preparation method are removed in a kind of structure demolition, and its raw material includes sand and cement, add water mixing all
Even.
Water with the weight ratio of sand and cement is：
Sand is the middle sand in 0.35-0.5mm for the particle diameter.
Cement is portland cement.
When sand is dried, the weight ratio of water and sand and cement is (1-1.2):(2-2.5):(1.2-
1.5) mix homogeneously；If sand is wetter, the proportion of sand can decrease.
After sand and cement mixing, add water mix homogeneously, and the amount adding water will arrive and can bring the mixture to hold with handss,
Till intact being bonded together.
