摘要

通过一系列的试验,认为正常细度的硅酸盐水泥与较细的高炉矿渣相结合,可以生产出较好的高炉水泥。将颗粒化炉渣磨至Blaine细度接近5000cm2/g,与3000cm2/g的硅酸盐水泥按不同比例混合。将混合料与普通砂配制成尺寸为40×92φmm的1:3砂浆试件,经水养护后,用自行设计的仪器测量了在约3mm H2O压力下的吸水率。利用细度为3000、4000和5000cm2/g的矿渣进行了类似的试验,以了解晶粒度的影响。砂浆试件的强度也进行了测试40×40×160mm尺寸。得到以下结果:(1)含60、70和80%大小的渣约5000 cm2 / g显示吸收低至3 - 15%的纯硅酸盐水泥的年龄后2到3周。(2)颗粒大小对吸收的影响随着年龄逐渐下降。(3)吸收与矿渣细度的增加下降。(4)在早期年龄的差异吸收两个包含3000和4000 cm2 / g矿渣水泥远远大于那些在4000和5000 cm2 / g炉渣。(5)吸收的差异造成的细度(6)与硅酸盐水泥相比,高炉水泥的吸收/蒸发比更小,说明尽管试样的下表面始终与水接触,但高炉水泥的干燥速率高于纯硅酸盐水泥。(8) 5000cm2/g粉料的高炉水泥两周强度高于硅酸盐水泥。

Capillary Water Absorption of Portland Cement Mortar Added with Large Quantities of Blast Furnace Slag
A series of experiments was carried out with an idea that better blast furnace cement may be produced by the combination of the portland cement of normal fineness with finer blast furnace slag. The granulated slag was ground to nearly 5000cm2/g of Blaine fineness to mix, in different ratios, with the portland cement of 3000cm2/g. Using the mixture and normal sand the specimens of 1:3 mortar of the size 40×92φmm were formed, and after water curing the water absorption under the pressure of about 3mm of H2O was measured with an apparatus of the author's own design. Similar experiments were carried out, using the slag of the fineness of about 3000, 4000 and 5000cm2/g in order to know the effect of grain size. The strength of the mortar specimens 40×40×160mm in size were also tested.The following results were obtained:(1) Blast furnace cement containing 60, 70 and 80% slag of the size of about 5000cm2/g showed the absorption as low as 3-15% of pure portland cement after the age of 2 or 3 weeks.(2) The effect of grain size on the absorption fell gradually with age.(3) The absorption decreased with the increasing fineness of slag.(4) In early ages the difference of absorption between two cements containing 3000 and 4000cm2/g slags was far larger than those between 4000 and 5000cm2/g slags.(5) The difference of absorption caused by the fineness of slag decreased with the increasing age of specimen.(6) Compared with portland cement blast furnace cement showed a smaller ratio of absorption/evaporation telling that it had a higher drying rate than pure portland cement notwithstanding the lower surface of the specimen was always in contact with water.(7) Furthermore, it was noticed that the blast furnace cement gave a larger amount of bleeding water and a smaller content of air when filled in mould.(8) The blast furnace cement of 5000cm2/g powder gave higher two weeks strength than portland cement.
