Airport road cement production process

Abstract

The invention discloses an airport road cement production process. A method mainly comprises the following steps: 1, proportioning four raw materials of high-quality limestone, fly ash, converter slagand silica to obtain a raw material; sequentially performing grinding, homogenization treatment, and high-solid-gas-ratio suspension preheating pre-decomposition, then firing the clinker in a novel dry-method rotary kiln, and carrying out cement milling on 96.0% of clinker, 4.0% of gypsum and 0.06% of grinding aid to prepare the cement. According to the invention, the alkali content in the cementis reduced, so that the physical quality of the cement is improvedand the hydration heat of the cement is reduced; therefore, the damage of alkali-aggregate reaction to concrete is prevented, the service life of the airfield pavement can be greatly prolonged, and the resource waste is reduced, so that huge economic and social benefits are generated.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to an airport road cement production process. Background technique

[0002] With the rapid development of high-level airport road traffic modernization, the development of cement concrete pavement has been placed in an important position in road construction. However, compared with asphalt pavement, concrete pavement has the advantages of longer service life, simpler construction and lower maintenance costs. Good wear resistance and impact resistance characteristics, so it is widely used in countries all over the world. Compared with the rapid development of airport road construction in foreign countries, the development of road Portland cement in China is relatively slow. At present, many airport road concrete pavements are seriously damaged in the early stage. In addition to the construction quality, it is also related to the fact that the majority of road construction...
