B), spreading diamond dust composite material is rubbed pressure for the first time, floating: total consumption of diamond dust composite material is every square metre of concrete surface 5kg, 60-90min before concrete initial set, diamond dust composite material with 2/3 total consumption, spread the position, corner earlier, shed big face then, the distance of positions of selling during spreading concrete 20～32cm, vertically straight line is sold, treat that material absorbs the moisture in the concrete, the surface occurs getting damp after color tarnishes, promptly begin for the first time floating, adopt the dispersion of milling of the finisher of dress disk, itself and substrate concrete slurry are combined, described diamond dust composite material is made by the following weight percentages combination: alumina 50～60%, iron oxide pigment 3～11%, nanometer (10～50nm) titanium dioxide 30～40%, metal aggregate wear-resistant hardener 5～10%.
C), for the second time spreading diamond dust composite material rub pressures, rub flat: be spread in uniform in concrete surface with the 1/3 diamond dust composite material that is about to remainder, spread the shop direction with for the first time vertical, carry out the floating work second time, finish troweling work with the finisher of dress blade at last;
D), maintenance: promptly begin maintenance after the final set of abrasion-proof terrace concrete, adopt the abrasion-proof terrace curing agent at sun straight shot places, consumption is 0.2 liter/m
2, or face covers plastic sheeting and prevents to cause cracking, at the not sprayable everywhere device wet curing of solar radiation such as basement, more than the curing time 7d.
The same substantially known technology of above-mentioned steps A, D.
The present invention mainly adopts the diamond dust composite material, wherein admixture metal aggregate wear-resistant hardener (commercially available various products) can improve the intensity and the compactness of wearing layer, intensity can reach more than the 100MPA, prevents terrace cracking, more high-strength, wear resistant and impact resistant, densification.
Advantage of the present invention is: (1) is compared with epoxy mortar terrace, epoxy resin terrace, abrasion resistance is strong, compressive strength is high, the economic dispatch characteristics, cost saves 10%～50%, and (2) are ageing-resistant, UV resistant, color never changes, and (3) speed of application is fast, and setting time is short, construct continuously with base material, shorten the construction period; (4) barrier performance is good, prolongs the concrete life-span; And it is easy to clean to give ground, keeps attractive in appearance.
