摘要

本文分析了在硅酸盐水泥CEM I 42.5R中分别以20:0、10:10、20:10、15:15的比例加入硅质和钙质粉煤灰混合料制备的硅酸盐复合水泥CEM II/B-M (V-W)的性能。Blaine水泥的表面积为4000±100 cm 2 /g。对水化热、标准稠度、初凝时间、稳固性和抗压强度进行了分析。当硅质粉煤灰与钙质粉煤灰的比例为20:10时，将水泥中的硅质粉煤灰部分替代得到强度等级为52.5N甚至52.5R的波特兰复合水泥CEM II/B-M (V-W)。

The possibility of use of mixture of siliceous and calcareous fly ash for production of Portland-composite cement type CEM II/B-M (V-W) 52.5

The paper analyses the properties of Portland-composite cement CEM II/B-M (V-W) prepared by addition of mixture of siliceous and calcareous fly ashes – in percentage proportion of 20:0, 10:10, 20:10 or 15:15 – to Portland cement CEM I 42.5R. Blaine’s surface area of cements equalled 4000 ± 100 cm 2 /g. Hydration heat, standard consistency, initial setting time, soundness and compressive strength were analysed in the paper. Partial replacement of siliceous fly ash with calcareous fly ash in cement gives a Portland-composite cement CEM II/B-M (V-W) of strength class 52.5N or even 52.5R, if the percentage proportion of siliceous to calcareous fly ash is 20:10.

期刊介绍： The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
