を調べると、これは著しく小さいものであった。[Industrial Field of Application 1] The present invention relates to polymer cement I/concrete 1/products and methods for producing the same. [Background of the Invention] So-called 1-reamer cement concrete has improved strength, water resistance, and stability (collectability, etc.) compared to ordinary concrete 1 due to the presence of polymer inside the concrete.
It is said that the first character is f base. Therefore, it is being considered to use it, for example, as an embedded formwork. However, polymer cement concrete has a large shrinkage strain (more than 1000 x 10-' when dry, ordinary concrete has a shrinkage of about 600 to 100 x 10-' when dried), and countermeasures are needed to deal with this. That is, for example, cement h 380-500Kg/m
' and 150 to 180 parts of water (about 1/n'), poured into a concrete frame of 2 indian concrete that had been adjusted to the desired properties, and after curing in water or in a humid air, submerged in the air. Polymer cement concrete is produced by curing. By the way, polymer cement concrete products produced in this way suffer from drying shrinkage during storage and usage environments. In particular, drying shrinkage occurs when drying is accelerated. If the product is left in the environment for a long period of time, it may warp, or if shrinkage and deformation are restricted during use, internal stress will occur, leading to a decrease in the strength of the product. It is important to reduce the drying shrinkage distortion of the product. [Disclosure of the Invention] The purpose of the present invention is to improve the drying shrinkage distortion in polymer cement I concrete. This is achieved by a polymer-cement concrete product characterized in that a binder and a polymer are interposed in the voids of aggregates that are blended so that the aggregate filling rate of concrete and fine aggregate is substantially maximized. In addition, when compacted by pressurized vibration, 1'Il aggregate and fine 1
A mixture of coarse aggregate, TA aggregate, powder binder, water, and polymer dispersion blended so that the aggregate filling Q1 rate of one material is substantially maximized is placed in a mold, and the mixture is subjected to pressurized vibration. It is also achieved by a method for producing polymer-cement concrete products, which is characterized by compaction. In other words, as a result of vigorous research and development by the present inventors, distortion due to drying shrinkage, etc. can be prevented by ensuring that the aggregates (coarse aggregates and fine aggregates) are tightly packed to exhibit a deformation restraining effect. I was nervous about what I could accomplish. Here, packing densely so as to exhibit a deformation restraining effect means that when a mixture of coarse aggregate and fine aggregate is subjected to vibration compaction of polymer cement concrete, the filling rate of aggregate is maximized by 1. This is achieved by pouring a mixture of aggregate and aggregate into a mold and performing pressurized vibration compaction. In addition, steel fiber and carbon! When manufacturing polymer cement concrete products containing fibers such as a-fibers or synthetic resin fibers, the mixing rate of the fibers is determined by the performance required of the product. In addition to this fiber, a mixture of coarse aggregate and coarse aggregate was added in the same row 1' as when forming the concrete product, with the mixing ratio of a fiber being set to a predetermined value.
When pressurized vibration compaction was performed at step α, after kneading coarse aggregate and fine aggregate in three parts and binder paste i so that the aggregate filling rate was maximized, This is achieved by pouring this material into a mold and subjecting it to pressure vibration compaction. Furthermore, since drying shrinkage deformation of concrete is thought to occur in the binder paste portion, it is preferable to reduce the unit amount of water as much as possible. For example, the water powder binder ratio is 2
It consumes about 5-30%. Here, the water/powder binder ratio is (amount of water in the polymer dispersion)/(amount of water added at the time of mixing)/(cement already (-)
This is the value determined by the amount of fly ash + amount of silica hume). Polymer dispersion, which improves the fluidity of concrete, accounts for 5 to 10% of the weight of the binder in terms of solid content.
It can be used to some extent. In addition, in order to further improve the fluidity of concrete 1 and mixing, fly ash with good particle shape (spherical shape) is used. It is also good to use activated silica such as silica hume as a part of cement for the purpose of improving acid resistance and acid resistance. Then, the above materials are mixed into a predetermined frame, and a predetermined unevenness (protrusion height of about 0.8 to 2 cII+, negative side of about 2 to 2 cm) is formed.
005 to 0 using a pressure plate formed with
．． A polymer cement concrete product with improved drying shrinkage distortion can be obtained by applying a pressure of approximately 112 h f/'cI to 2 and performing vibration molding. The concrete product obtained in this way is in a state close to that of an instant demolding concrete product, so even if the molding is immediately removed from the pressure plate, the unevenness formed on the concrete product by the pressure plate will remain in its shape. is held. Furthermore, if a steam curing shade is applied with the bottom and side plates of the formwork attached, a concrete product close to that of an instant demolding product but with a beautiful finished surface can be obtained. The above-mentioned unevenness of the pressure plate improves the compaction of concrete by making it difficult for the aggregate to move during pressurized vibration molding, and also improves the compaction properties of the concrete when using Polymer Cement I/concrete products as buried formwork. The unevenness transferred from the unevenness of the pressure plate increases the adhesion with the concrete poured on site. The unevenness can be easily formed by simply removing the pressure plate after pressure vibration molding.
