The present invention relates to a method for manufacturing concrete blocks, and more specifically, the epoxy resin mortar consisting of a hydrophobic epoxy resin and a hardening agent has a water-to-cement ratio of 10 to 40%.
The present invention relates to a method for manufacturing concrete blocks, which is characterized in that the concrete blocks are laminated on or under unhardened cement concrete and simultaneously pressure-molded. Various types of concrete sidewalk boards are used for promenades, park plazas, plazas in front of buildings, etc., and have the advantages of being relatively easy to construct and easy to repair even when paved on a soft roadbed. It is rapidly becoming popular due to its Concrete blocks for flower beds and blocks for external walls of buildings are also becoming popular due to aesthetic reasons due to precasting. However, although these surfaces are often colored, since colored cement is used, there remains the problem that they become white and reduce the commercial value of colored products. As long as colored cement is used, the slaked lime component in the cement will react with carbon dioxide gas in the atmosphere to produce calcium carbonate.
This results in a whitening phenomenon, so preventing whitening is fundamentally a difficult problem. The present invention aims to improve this drawback of whitening and at the same time provide a method for manufacturing concrete blocks having a one-shot colored epoxy resin mortar on the surface. Since cement concrete still contains water, it is difficult to bond with epoxy resin mortar, which is an organic compound. However, according to research conducted by the present inventors, adhesion has become possible by using a hydrophobic epoxy resin and adjusting the moisture content in cement concrete that has not yet hardened to an appropriate level. If both the epoxy resin and the curing agent are water-soluble, the adhesive force will be extremely low no matter how you control the amount of water in the unhardened cement concrete. Hydrophobic epoxy resins used in the present invention include bisphenol A diglycidyl ether, bisphenol A propylene oxide diglycidyl ether, polyoxypropylene diglycidyl ether, dimer acid glycidyl ester, phthalate glycidyl ester, and phenol novolac glycidyl ether. Among them, bisphenol A diglycidyl ether is particularly preferred. Epoxy resin curing agents used in the present invention include octylamine, laurylamine, oleylamine, linoleylamine, octylpropylene diamine, laurylpropylene diamine, oleylpropylene diamine, linoleylpropylene diamine, oclodipropylene diamine, laurodipropylene diamine, oleodipropylene diamine,
Heptadecenylimidazoline polyamine, dimer acid polyamide amine, xylene diamine, polymercaptan, polysulfide resin, ethylene diamine, diethylene triamine, polyoxypropylene diamine, polyethylene imine, benzyl ethylene diamine, etc. can be used, but in particular, the following general formula (1) ~ Compounds represented by (5) are preferred. RNH 2 (1) RNH (CH 2 ) o NH 2 (2) RNH (CH 2 ) o NH (CH 2 ) o NH 2 (3) (In formulas (1) to (4), R is an alkyl group having 8 to 22 carbon atoms or an alkenyl group having 8 to 22 carbon atoms, n is an integer of 2 to 3, and m is an integer of 1 to 5) R'OAp ( CH 2 ) 3 NH (CH 2 ) 3 NH 2 (5) (In formula (5), R' is an alkyl group having 8 to 22 carbon atoms, an alkenyl group having 8 to 22 carbon atoms, or an alkyl group having 8 to 22 carbon atoms. (A is an oxypropylene group, p is an integer of 0 to 20) Particularly preferred are fatty polyamines such as oleic propylene diamine and linoleyl propylene diamine. The amount of water in the cement concrete that has not yet set affects the adhesive strength between the epoxy resin mortar and the cement concrete. Water cement ratio is 10
It is necessary to be in the range of ~40%. If the water-cement ratio exceeds 40%, the liquid nature of the cement concrete becomes high, and no improvement in strength can be expected through compression molding, and even pressure-formed concrete blocks may lose their shape after demolding because they are easily demolded. .
If the water-cement ratio is less than 10%, the amount of water required to harden the cement is too small, resulting in insufficient hardening. Epoxy resin mortar on concrete surface
Since the thickness is about 0.3 to 1 cm, it is preferable to use aggregate with a particle size of 5 mm or less. The amount of resin may be at least the amount necessary to maintain strength, and may be at least 2% in the mortar. Prime coat may be used, or even if it is not used, it will not separate between the concrete and the resin mortar. Example 1 Preparation of cement mortar Cement 120Kg/m 3 , River sand 230Kg/m 3 , Water 36Kg/m 3
m 3 (30% water/cement ratio) was used. Preparation of epoxy resin mortar 10 parts by weight of various epoxy resins, 66 parts by weight of No. 5 silica sand, 18 parts by weight of No. 7 silica sand, and 6 parts by weight of filler were thoroughly mixed to prepare. However, the epoxy resin is a mixture of the epoxy equivalent part of the base resin and the active hydrogen equivalent part of the curing agent. Preparation of specimen Cement mortar was poured into a 6 cm thick iron cylinder with a depth of 10 cm and a diameter of 12 cm.
A resin mortar with a thickness of cm was placed and compression molded for 30 seconds using an Amsler at a pressure of 50 kg/cm 2 . It was cured at room temperature for 14 days and used as a specimen for measuring adhesive strength. Adhesion Test After the attachment was bonded so that the adhesive force between the cement mortar layer and the resin mortar layer could be measured, the adhesive force was measured according to ASTM D897. The results are as follows.

る。[Table] As is clear from the results, hydrophilic epoxy resins cannot be used, but hydrophobic epoxy resins can be used. Preferably, the curing agent is also hydrophobic. Example 2 Cement 150Kg/m 3 , River sand 290Kg/m 3 , Water 60Kg/m 3
The procedure was carried out in the same manner as in Example 1 using a cement mortar with a composition of m 3 (water/cement ratio 40%), using an epoxy resin with bisphenol A diglycidether as the main agent and oleyl propylene diamine as the hardening agent. After aging, no destruction of the interface was observed. The colored concrete block manufactured by this method has an upper epoxy resin layer that prevents the lower cement concrete or cement mortar from coming into contact with carbon dioxide gas and moisture in the atmosphere, making it difficult for the aforementioned whitening to occur. . Also,
At the same time, the properties of the resin such as chemical resistance, durability, abrasion resistance, and slip resistance are further improved.
