Embodiment Construction

[0039] In concrete implementation, the proportioning of parts by weight of each component in the cement concrete color admixture is:

[0040] 100g of iron black, 30-60g of carbon black, 0.4-0.8g of sodium hexametaphosphate, 4.0-9.0g of composite early-strength and high-efficiency superplasticizer, and 40-50g of expansion agent.

[0041] It can be specifically: iron black 100, carbon black 50, sodium hexametaphosphate 0.75, composite early strength superplasticizer 8.5, expansion agent 42.5.

[0042] Among them, the composite early strength reducer is a commercially available product, and its ingredients include: β-naphthalene sulfonate sodium formaldehyde high condensate and a reinforcing agent. Wherein, the reinforcing agent is sodium sulfate. Using industrial naphthalene as the raw material, the monomer is sulfonated by concentrated sulfuric acid at the β position of the naphthalene ring, and then formaldehyde is used as the catalyst to condense the sulfonated monomer into ...

Abstract

The color additive consists of coloring agent, dispersant, composite early strength effective water reducing agent and swelling agent. Specifically, it consists of iron black or carbon black as coloring agent, calgon or STPP as dispersant, water reducing agent and potassium aluminum sulfate as swelling agent. The color additive can change the color of cement concrete and improve the performanceof cement concrete. Specially, when the cement concrete with the color additive is used in the extension joint of asphalt bridge surface of expressway, the less color difference can raise the safetyof running vehicles.

Description

Technical field: [0001] The present invention relates to cement concrete. Background technique: [0002] With the ever-increasing traffic volume, large-scale vehicles and the increasing proportion of heavy-loaded and overloaded vehicles, the traffic has higher and higher requirements for the performance of the road surface, especially for road traffic safety, comfort and environmental protection. Higher expectations . Therefore, the pavement of the road must have excellent skid resistance, better durability, low noise, and no water mist and no glare in a wet state. Among many structural types of pavement, asphalt concrete pavement is gradually accepted due to its excellent road performance, and has become a new structural form in high-grade highway engineering. However, its poor durability is still a technical problem, especially in the use of bridge expansion joints. Concrete used in bridge expansion joints must meet the following conditions in terms of durability: 1. Hi...
