42 | Redispersible polymer powders prepared from low carboxylation styrene butadiene-based latex | EP11161357.6 | 2011-04-06 | EP2380927A1 | 2011-10-26 | Kim-Habermehl, Linda H.; Ladika, Mladen; Hong, Liang |
A water redispersible polymer powder is produced by drying an aqueous mixture of a low carboxylation, low Tg, large average particle size water insoluble film-forming polymer latex or emulsion and a colloidal stabilizer. The latex polymer may have an average particle size of 2000Å to 5,000Å, and an amount of carboxylation of 0.1% to 2.75% by weight of at least one ethylenically unsaturated dicarboxylic acid, salts or mixtures thereof, based upon the weight of the polymer. Dispersions containing the polymer and a polyvinyl alcohol as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. Cement compositions such as mortars, which contain the redispersible polymer powder exhibit unexpectedly lower rates of viscosity buildup for better workability or troweling, faster set time, and superior heat flow characteristics. |

The invention relates to a method for producing aggregates from non-hardened cement compositions, in particular from concrete or residual concrete, which method comprises adding a) a water-absorbing agent and b) a crystallization deactivator to a non-hardened cement composition and mixing until a granular material has formed. The method allows unneeded residues of still liquid concrete to be converted into a practical product, which can then be reused to produce new concrete compositions. The invention further relates to a granulated cement material that can be obtained according to a corresponding method, to the use of said granulated cement material as an additive for cement compositions, and to additive combinations for cement compositions, which additive combinations comprise a water-absorbing agent and a crystallization activator. | ||||||

A water redispersible polymer powder is produced by drying an aqueous mixture of a carboxylated styrene butadiene polymer and a colloidal stabilizer which includes a polyvinyl alcohol modified with an alkyl end chain. The alkyl modified polyvinyl alcohol provides excellent redispersibility of the redispersible polymer powder without adversely affecting spray drying. Cement compositions such as mortars, which contain the redispersible polymer powder with the alkyl modified polyvinyl alcohol exhibit unexpectedly superior stability and an unexpectedly lower rate of mortar viscosity buildup which is advantageous for workability or troweling. |

PROBLEM TO BE SOLVED: To provide a cement composition having excellent bleeding resistance, which exhibits good flowability when it is applied with shearing force during pump pressure-feeding or the like, but has high thixotropic property (dripping preventing property) even when the amount of water is increased without using a quick-setting agent, and which is less likely to cause bleeding when it is cured and almost free from volume shrinkage after curing. SOLUTION: In a cement composition comprising cement (a) and water (b), the cement composition contains crosslinked acrylic polymer particles (c) and an alkylether-modified cellulose resin (d). In the cement composition, the weight ratios of the contents of respective components are as follows: (a)/(b)=100/40-100/100, (c)/(b)=1/500-1/100, (d)/(b)=1/1,000-1/100, and (c)/(d)=1/1-10/1, and the crosslinked acrylic polymer particles (c) are water-insoluble powder composed of crosslinked acrylic polymer particles containing sulfonic acid group and/or acrylamide group.
