Definitions
- the present invention relates to the use of polymeric microparticles in hydraulically setting building material mixtures to improve their Frostg. Freeze-thaw resistance.
- the concrete has two time-dependent properties. First, it experiences a decrease in volume due to dehydration, which is called shrinkage. However, most of the water is bound as water of crystallization. Concrete does not dry, it binds, that is, the initially low-viscosity cement paste (cement and water) stiffens, solidifies and finally solidifies, depending on the timing and sequence of the chemical-mineralogical reaction of the cement with the water, the hydration. Due to the water-binding capacity of the cement, the concrete, in contrast to calcined lime, can also harden under water and remain firm. Secondly, concrete deforms under load, the so-called creep.
- the frost-thaw cycle refers to the climatic change of temperatures around the freezing point of water.
- the frost-thaw cycle is a damaging mechanism. These materials have a porous, capillary structure and are not waterproof. If such, water-soaked structure exposed to temperatures below 0 0 C, the water freezes in the Pores. Due to the density anomaly of the water, the ice now expands. This leads to damage to the building material. In the very fine pores due to surface effects, the freezing point is lowered. In micro pores, water only freezes below -M 0 C. Since the material itself also expands and contracts due to freeze-thaw cycles, there is an additional capillary pumping effect that further increases water absorption and thus indirectly the damage. The number of freeze-thaw cycles is therefore decisive for the damage.
- the structure of a cement-bound concrete is traversed by capillary pores (radius: 2 ⁇ m - 2 mm) or gel pores (radius: 2 - 50 nm). Pore water contained therein differs in its state form depending on the pore diameter.
- a prerequisite for an improved resistance of the concrete during frost and thaw changes is that the distance of each point in the cement stone from the next artificial air pore does not exceed a certain value. This distance is also referred to as the "distance factor” or “powers spacing factor” [TCPowers, The air requirement of frost-resistant concrete, "Proceedings of the Highway Research Board” 29 (1949) 184-202]. Laboratory tests have shown that exceeding the critical "Power spacing factor" of 500 ⁇ m leads to damage to the concrete during frost and thaw cycles. In order to achieve this with a restricted air-pore content, the diameter of the artificially introduced air pores must therefore be less than 200-300 ⁇ m [K.Snyder, K. Natesaiyer & K.Hover, The stereological and Statistical properties of entrained air voids in concrete: A mathematical basis for air void system characterization) "Materials Science of Concrete” VI (2001) 129-214].
- an artificial air pore system depends largely on the composition and grain size of the aggregates, the type and amount of cement, the concrete consistency, the mixer used, the mixing time, the temperature, but also on the type and amount of the air entraining agent. Under consideration of the appropriate manufacturing rules, their effects can indeed be mastered, however, there may be a large number of undesired impairments, which ultimately leads to the desired air content in the concrete can be exceeded or fallen below and thus adversely affected the strength or frost resistance of the concrete ,
- Such artificial air pores can not be metered directly, but by the addition of so-called air-entraining agents, the air introduced by mixing is stabilized [L. Du & K.J. Folliard, Mechanism of air entrainment in concrete "Cement & Concrete Research” 35 (2005) 1463-71].
- Conventional air entraining agents are mostly of a surfactant-like structure and break the air introduced by the mixing into small air bubbles with a diameter as small as possible of 300 ⁇ m and stabilize them in the moist concrete structure. One distinguishes between two types.
- These hydrophobic salts reduce the surface tension of the water and accumulate at the interface between cement grain, air and water. They stabilize the microbubbles and are therefore found in the hardening concrete on the surfaces of these air pores again.
- the other type e.g. Sodium lauryl sulfate (SDS) or Natriumdodecylphenylsulfonat - on the other hand forms with calcium hydroxide soluble calcium salts, but show an abnormal solution behavior. Below a certain critical temperature these surfactants show a very low solubility, above this temperature they are very soluble. By preferentially accumulating at the air-water interface, they also reduce the surface tension, thus stabilizing the microbubbles, and are preferably found on the surfaces of these air voids in the hardened concrete.
- SDS Sodium lauryl sulfate
- Natriumdodecylphenylsulfonat forms with calcium hydroxide soluble calcium salts, but show an abnormal solution behavior. Below a certain critical temperature these surfactants show a very low solubility, above this temperature they are very soluble.
- microparticles described therein have diameters of at least 10 microns (usually much larger) and have air or gas-filled cavities. This also includes porous Particles, which can be greater than 100 microns and can have a variety of smaller cavities and / or pores.
- the object was achieved by the use of polymeric microparticles having a cavity in hydraulically setting building material mixtures, characterized in that gas-filled microparticles are used. As gas-filled microparticles become spray-dried core. Shell polymers used. The gas-filled microparticles are already effective when mixed into the building material mixture, since no water must diffuse out of the particle interior. This ensures a good frost or freeze-thaw resistance virtually immediately after hardening of the building material mixtures.
- the notation (meth) acrylate as used herein means both methacrylate, e.g. Methyl methacrylate, ethyl methacrylate, etc., as well as acrylate, e.g. Methyl acrylate, ethyl acrylate, etc., as well as mixtures of both.
- microparticles according to the invention can preferably be prepared by emulsion polymerization and preferably have an average particle size of 100 to 5000 nm; particularly preferred is an average particle size of 200 to 2000 nm. Most preferred are average particle sizes of 250 to 1000 nm.
- the mean particle size is determined, for example, by counting a statistically significant amount of particles on the basis of transmission electron micrographs.
- the microparticles When prepared by emulsion polymerization, the microparticles are obtained in the form of an aqueous dispersion.
- microparticles are already known according to the prior art and are described in the publications EP 22 633 B1, EP 73 529 B1 and EP 188 325 B1.
- these microparticles are commercially sold under the brand name ROPAQUE® by Rohm & Haas. These products have heretofore been mainly used in inks and inks to improve the opacity and opacity of paints or prints on paper, board and other materials.
- the cavities of the microparticles are water-filled.
- the dispersion is spray-dried. Spray drying removes the liquid from the core-shell polymer particles. There are obtained gas-filled hollow microspheres, which are very stable.
- the microparticles used consist of polymer particles which have a core (A) and at least one shell (B), the core / shell polymer particles having been swollen with the aid of a base.
- the core (A) of the particle contains one or more ethylenically unsaturated carboxylic acid (derivative) monomers which allow swelling of the core; these monomers are preferably selected from the group of acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid, itaconic acid and crotonic acid and mixtures thereof. Acrylic acid and methacrylic acid are particularly preferred.
- the shell (B) predominantly of nonionic, ethylenically unsaturated monomers.
- Preferred such monomers are styrene, butadiene, vinyltoluene, ethylene, vinyl acetate, vinyl chloride, vinylidene chloride, acrylonitrile, acrylamide, methacrylamide, C1-C12-alkyl esters of (meth) acrylic acid or mixtures thereof.
- the gas-filled microparticles are added to the building material mixture in a preferred amount of from 0.01 to 5% by volume, in particular from 0.1 to 0.5% by volume.
- the building material mixture - for example in the form of concrete or mortar - can here the usual hydraulically setting binder such.
- cement lime, gypsum or anhydrite.
- the advantage according to the invention is manifested above all in the weathering factor, which represents a qualitative assessment of the optically visible frost damage on the surface of a sample.
- the uncontrolled introduction of air into the building material mixture can be kept extremely low.
