B7 V. Description of the Invention (1) Waterproofing is the most important issue for the durability of cement. The depreciation of most cements is due to the high permeability and absorption of cement to water and the entry of dissolved gas and sulfate ions into the water, causing not only the participation of water but also the corrosion of steel bars and the expansion of cement damage. . Silica fume, a by-product of silicon or ferrosilicon products, is commonly used as a cement and cement additive to make anti-corrosive cement. Cement has improved mechanical properties or waterproof cement (see, for example, US 4 , 118,242, US 4,310,486 and US 5,472,501). However, its shortcomings are poor applicability and relatively quotient surface water absorption due to the capillary action of good pores, which causes the cement to be highly absorbent and therefore high-potential gas / sulfate is established on the offshore cement structure Splash and tidal zone. In addition, high water absorption will result in a cement that is water-resistant but non-moisture-resistant and cannot be used in general. The specifications of the water absorption plan are less than 1% of cement when tested according to BS1881: Partl22. Hydrophobic compounds such as calcium stearate, silicon, wax or asphalt emulsions are also commonly used as waterproofing mixtures of cement to give the capillary surface a hydrophobic coating and block some holes. However, some compounds have the disadvantage of reducing Compressive force (typically 10-15% less than the crude cement) and reduces effectiveness on top of high fluids. However, a low water permeability and low absorption to a durable waterproof cement is sought. One solution is to separately add the smectite smog and hydrophobic compounds in the process of making the cement. However, this requires additional mixing / dispersion and the hydrophobic compound is usually added as a milk to achieve a homogeneous mixing. The pre-emulsification of the hydrophobic compound and the complex formulation method make this paper size applicable to the Chinese National Standard (CNS) A4 specification (2! 0 × 297 male f) (please read the precautions on the back before filling this page). -

In fact, increased compressive forces were found in many examples. Variations in the data of this force attributed the rough cement system to different sources of cement that were tested at different times. The comparison should therefore be limited to each group tested. Modification of hardeners with butyl stearate shows the best binding power for strength development and water absorption. Similar cements can be prepared to use a mix of more than one waterproofing additive. More than one setting material can be used, and the or each setting material can be modified with the same or different sulfur aqueous materials or with more than one hydrophobic material. Example 2-Waterproofing of cement The effect of this waterproofing additive on cement is demonstrated by the following studies. The modified hardened substance used in this study was thickened silica fume (as detailed in Table 1) modified with 10% butylstearate. Other hardening materials modified with butylstearate are expected to show similar or better results as shown in this cement slurry study.

The permeability is set to ENV206 cement which cannot penetrate water. This water absorption can also be controlled to less than 1%. Different waterproof additives, or mixtures of additives, as described for Example 1 can be used to equip cement as in this example. One of the additional benefits of the new waterproofing agent described above is the reduced water absorption of the modified cement. The absorption test is actually similar to the surface water absorption test. The only difference is that the sample in this example is not completely immersed in water, but only the bottom surface of the test sample is placed in contact with water. In this way, capillary absorption can be observed directly with the inner eye to observe the increase in height in the wet zone, or Measure the weight increase. The following example demonstrates the absorption behavior of cement under capillary forces. The cement mix used for the test was shown in Example 2 with a 10% additional modified silica fume, and a cement system prepared with 10% unmodified silica fume for comparison. The cement system was corrected for 28 days and the core part had a diameter of 75mm and a height of 75mm were selected. The sample was coated with an epoxy resin in the longitudinal direction of the longitudinal plane and dried in an oven 1051: 3 days and cooled in a drying box for 1 day before testing. The test sample was placed in contact with water at the bottom of the cylinder and the weight increase of the sample was measured after 30 and 60 minutes and 24 hours after contact with water. The sample is divided into two halves after 24 hours and the wet paper size applies the China National Standard (CNS) A4 specification (210X297). T5 I -------- -Shiΰί-nn __ Ding Yi η »I ------ 15 · 0¾, νβ〆 (Please read the precautions on the back before filling out this page) 438734 μ B7 One-fifth Ministry of Economic Affairs Central Standards Bureau Employees' Cooperative Cooperative Printed Invention Description (13) The height is measured. The results are shown in Table 10. Table 10: Water Absorptivity of Rental Cement, Modified Silica Fume Cement with Silica Fume_Comparison_ Cement Raw SF-Cement MSF-Cement W / C Ratio 0.36 0.45 0.36 0.45 0.36 0.45 Weight Increase 30 minutes 2.5 4.2 1.9 3.9 0.4 1.0 60 minutes 4.0 7.5 3.2 5.9 0.9 1.9 24 hours 13.8 22.8 10.2 17.6 3.0 5.1 Wet zone height_ 24 hours (mm) 51 63 38 48 4 10 In fact, the absorption capacity of the silica fume cement is also The line is very high, due to the appearance of good pores. The hydrophobically modified silica fume system is quite effective in reducing the capillary absorption of the cement. It is very useful for a durable cement to prevent the rise of moisture and the formation of weathering, and to reduce the concentration of gas and sulfate. The cement's moist silicon zone and splash zone reduce the damage of frozen ice and reduce the growth of algae on the cement surface. All in all, the improved waterproofing agent described above is noted to provide an improved and economical solution for the construction of highly durable water impermeability and moisture-proof cement which can overcome the relatively high waterproof cement containing silica fume. Disadvantages of water absorption and reduced compressive forces, the relatively high water permeability of waterproof cements containing hydrophobic compounds. It can be found that the waterproof cement can be manufactured by adding a modified hardening substance to achieve the water resistance of cement such as ENV208 and less than 1% water absorption according to BS1881: Partl22. As in the example described above, the action of the hardening substance is the hydrophobic compound 16 (Please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X29 · / mm) 438734 A7 B7 V. The carrier of the invention description (14) and therefore is not needed for a pre-emulsification system, providing an essential advantage over previous techniques. The hardener pairing technique uses a reaction pore filler to reverse the hydrated product of the cement to form an insoluble precipitate which reduces its porosity and the pore size of the cement clay. At the same time, the absorbed hydrophobic compound is believed to move to the air / water interface of the cement and form a sparse outer layer on the cement surface and the walls of the pores, which can effectively protect the capillary absorption of water. The new water repellent described above has been found to provide a very effective solution for cement to have water impermeability and moisture resistance. The use of this waterproofing agent is quite straightforward and is different from the general use of silica fume in cement manufacturing. In fact, the working efficiency of new cement containing the new waterproofing agent was found to be better than that of ordinary clay soil cement. To an internal lubricant for the cement substance. The invention of the statement may include any feature or combination of features disclosed herein, whether implicitly or explicitly or any resulting therefrom, regardless of the invention of the statement. From the viewpoint described earlier, in fact, various improvements to people who are familiar with this technique can be made within the scope of this invention.
