Fang Wei: cement: 96%；Latex powder: 1%；Polypropylene fibre: 1%；Cellulose ether: 2%.Table 1-1 is basic recipe dry powder and mortar
Performance parameter, table 1-2 is the strike note sound insulation value of basic recipe dry powder and mortar, according to the determination of strike note Rating of the single value amount
Method, determines that the Rating of the single value amount of the strike note sound insulation of dry powder and mortar under basic recipe is 78.0dB, more than lower bound requirement
(75.0dB)。
The performance parameter of table 1-1 basic recipe dry powder and mortar
Table 1-2 basic recipe dry powder and mortar strike note sound insulation value parameter
Cellulose ether is the derivant of fibres of natural materials element, and the effect of its maximum can increase the stickiness of liquid exactly,
Playing thickening power, keep containing enough moisture in dry powder and mortar in the longer time meanwhile, water plays between each component
The effect of lubricant and solvent, it is simple to dry powder and mortar carries out combing, dry powder and mortar of plastering shakeouts, so cellulose ether can
To bring quick and economic construction effect, if without cellulose ether, dry powder and mortar can quickly parch, make the cement cannot be with
Normal mode aquation, thus dry powder and mortar cannot harden and cannot obtain the bonds well performance to basic unit.No. 1 of table 2-1
Dry powder and mortar formula is: cement: 94%-98%；Latex powder: 1%；Polypropylene fibre: 1%, cellulose ether: 0%-4%.From table
2-1 it can be seen that along with the increase of cellulose ether volume, the humidity of dry powder and mortar is increasing, the comprcssive strength of dry powder and mortar
Have certain increase with adhesion strength, but increase to that to change the most afterwards be not very big, and the cellulose ether of excess
Addition, due to water retention property increase after, too much moisture can cause the intensity of dry powder and mortar to decline, and delays the water of cement
Change dynamic process, it is therefore desirable to the strict volume controlling cellulose ether, when the content of cellulose ether is at 0.4%-3%, dry powder
The comprcssive strength of mortar, adhesion strength, final setting time are the most preferable.
The impact on properties of dry-mixed mortar of the table 2-1 cellulose ether
Cement in hardening process, have that fragility is big, Tension-compression specific intensity is low, dry-shrinkage deformed big, elongation percentage is low, crack resistance
The defects such as difference, adhesion strength are low, barrier properties, corrosion resistance difference, and after adding latex powder, properties of dry-mixed mortar can be caused a series of
Change, such as reduced stiffness, enhancing flexible, impervious, deformability, adhesion strength and durability improve.No. 2 of table 3-1 are done
Powder mortar formula is: cement: 94%-97%；Latex powder: 0-3%；Polypropylene fibre: 1%, cellulose ether: 2%.From table 3-1
It can be seen that along with latex powder volume increases, the comprcssive strength of dry powder and mortar has a small amount of raising, and adhesion strength is continuously increased,
Backfin ratio is gradually lowered, and toughness improves.When the content of latex powder is 0.5%-2%, the adhesion strength of dry powder and mortar has relatively
Big raising, and comprcssive strength and final set strength are all in more rational scope.
The impact on properties of dry-mixed mortar of the table 3-1 latex powder
Polypropylene fibre is the synthetic fibers that the isotactic polypropylene obtained with propylene polymerization spins for raw material.Density is
0.90-0.92g/cm3, there is intensity height, good springiness, feature wear-resisting, corrosion resistant.Owing to fragility and plastic shrinkage are dry powder sand
The defect of slurry itself, serious cracking can affect the quality of dry powder and mortar, makes the impermeability of dry powder and mortar, durability decline, though
After so adding latex powder, the toughness of dry powder and mortar can increase, but its crack resistance improves not enough, at harsh climate environment
In easily produce crack occurrence.And plastic shrinkage is relatively big, in order to improve dry powder and mortar crack resistance and impact resistance, add poly-
Tacryl, and be evenly distributed in dry powder and mortar, the tensile strength of dry powder and mortar, impermeability can be effectively improved, reduce
Dry powder and mortar produces micro-crack in hardening process and stops it to extend, and increases the fracture toughness of dry powder and mortar.No. 3 of table 4-1
Dry powder and mortar formula is: cement: 94%-97%；Latex powder: 1%；Polypropylene fibre: 0%-3%, cellulose ether: 2%.From table
4-1 is it can be seen that along with the increase of polypropylene fiber, the comprcssive strength of dry powder and mortar and adhesion strength have a certain degree of
Reduce, this be due to the incorporation of polypropylene fibre cause dry powder and mortar can density decrease thus porosity increased
Greatly.The incorporation of polypropylene fibre is the most, and the generation of minimizing dry powder and mortar crackle and the probability of development are the biggest, but mix too much, dry
The workability of powder mortar is poor.The content of polypropylene fibre is between 0.5%-2%, and the comprcssive strength of dry powder and mortar, bonding are strong
Degree, final setting time are preferable.
The impact on properties of dry-mixed mortar of the table 4-1 polypropylene fibre
Table 4-2 is the impact on dry powder and mortar bleeding of the different length polypropylene fibre, with the base being not added with polypropylene fibre
Quasi-mortar is compared, and the incorporation of polypropylene fibre reduces cement mortar bleeding, constant at other Stock allotment right, from admixture etc.
From the point of view of the bleeding that the polypropylene of amount different length receives, fibre mortar bleeding becomes negative correlation with the length of polypropylene fibre,
Considering the price of different length polypropylene fibre, 6mm polypropylene fibre bleeding rate can meet the demand of mortar.
The impact on dry powder and mortar bleeding of the table 4-2 different length polypropylene fibre
| Polypropylene fibre length | 0mm | 3mm | 4mm | 6mm | 12mm | 20mm |
| Bleeding rate/% | 0 | 5.1 | 5.0 | 4.6 | 4.4 | 4.0 |
Table 4-3 is the impact on dry powder and mortar comprcssive strength of the polypropylene fibre of 6mm, 11mm, 17mm of commonly using on the market,
Along with the change of the volume of polypropylene fibre, the tensile strength of mortar presents downward trend after first rising, and 6mm long fibre is mixed
Amount tensile strength between 0-0.5% keeps constant, and it is that tensile strength reaches maximum that 6mm long fibre volume reaches 0.5%, it
After the most constantly decline, and the optimum of 11mm polypropylene fibre and 17mm polypropylene fibre is respectively 2% and 2.5%, it is contemplated that
Financial cost, the bleeding of mortar and consideration polypropylene fiber characteristic of mortar between 0.5%-2%, 6mm's is poly-
Tacryl is optimal choice.

5-1 is it can be seen that along with the addition of glass bead volume, the density of dry powder and mortar, coefficient of softing, comprcssive strength, adhesion strength
It is gradually lowered.This is owing to the apparent density of glass bead is less than the apparent density of cement, and glass bead is hollow knot
Structure, when its volume increases.Dry powder and mortar internal voids increases, and causes the density of dry powder and mortar and intensity to reduce, but by table
5-1 can be seen that, when the content of glass bead reaches 30%, that the comprcssive strength of dry powder and mortar reduces and few, glass bead
Content between 30%-35%, the comprcssive strength of dry powder and mortar, adhesion strength, final setting time are preferable.
The impact on properties of dry-mixed mortar of the table 5-1 glass bead volume
Table 5-2 is that glass bead accounts for the content of dry powder and mortar when being 30%, and the strike note performance of dry powder and mortar, from table 5-2
Data analysis, determine that the Rating of the single value amount of the strike note sound insulation of dry powder and mortar under this formula is 72.0dB, ratio is under basic recipe
The Rating of the single value (78.0dB) of dry powder and mortar strike note will low 6.0dB.

Degree has declined, and the backfin of dry powder and mortar ratio reduces, and contraction gradually decreases, when dry powder and mortar admixture rubber powder reaches a certain amount of
Time, gum elastic powder is internal widely distributed at dry powder and mortar, and dry powder and mortar is contracted to a certain degree, and rubber is compressed can produce bullet
Property reply, contraction is weakened severely.When gum elastic powder is 9%, it is few that the adhesion strength of dry powder and mortar reduces, and works as elasticity
Rubber powder is when 9%-14%, and the comprcssive strength of dry powder and mortar, adhesion strength, final setting time are the most proper.
The impact on properties of dry-mixed mortar of the table 6-1 gum elastic powder
Table 6-2 is that gum elastic powder accounts for dry powder and mortar content when being 9%, and the strike note performance of dry powder and mortar, from table 6-2's
Data analysis, determines that the Rating of the single value amount of the strike note sound insulation of dry powder and mortar under this formula is 56.0dB, and ratio is under basic recipe
The Rating of the single value (78.0dB) of dry powder and mortar strike note will low 22.0dB.
