Problems solved by technology

[0003] Low production efficiency, consume a lot of human resources, long construction period
On-site construction mainly adopts manual work, and product quality is not easy to guarantee
Great environmental pollution, on-site concrete pouring produces noise, sewage, waste and other environmental pollution
When the pavement is demolished or abandoned, the pavement materials will form construction waste, which cannot be reused, resulting in a waste of resources
Construction is greatly affected by the climate
Rainy and cold seasons are unfavorable for construction, resulting in longer seasonal downtime
Therefore, the above shortcomings of cast-in-place concrete roads have become a bottleneck restricting the industrialization of concrete roads

Embodiment 1

[0017] In Example 1, a sample of vanadium pentoxide, mineral admixture, and cement 2:70:500 (unit parts) was prepared. 2 parts of vanadium pentoxide, 70 parts of mineral admixtures, 500 parts of cement, 80 parts of polyethylene glycol emulsion, 1000 parts of tap water, 0.5 parts of sodium lauryl sulfate (K12) air-entraining agent, polycarboxylic acid water reducing agent 2 parts of agent and 10 parts of deionized water.

[0018] Step 1. Prepare a sealed container with a size of 1×2×2m, put 70 parts of mineral admixture (mineral powder, coal ash 1:1) into the sealed container, use a vacuum pump to vacuum to a negative pressure of 0.08MPa, and then Inject polyethylene glycol emulsion into the container, the content of polyethylene glycol emulsion is 40% (mass), and let it stand for 2 hours under stable negative pressure, and the mineral admixture (slag powder, coal ash 1: 1) Curing for 3 days at a relative humidity of 60±5% and a temperature of 25±2°C to obtain an antifreeze pretr...

Embodiment 2

[0029] In Example 2, a sample of vanadium pentoxide, mineral admixture, cement 2:70:500 (unit parts) was prepared. 5 parts of vanadium pentoxide, 80 parts of mineral admixtures, 480 parts of cement, and the amount of other raw materials. The operation steps are the same as in Example 1.

Embodiment 3

[0030] In Example 3, a sample of vanadium pentoxide, mineral admixture, and cement 2:75:500 (unit parts) was prepared. 2 parts of vanadium pentoxide, 75 parts of mineral admixture, 500 parts of cement. The amount of other raw materials is the same as in Example 1.

Abstract

The invention discloses an assembled concrete road. The assembled concrete road is characterized by comprising concrete block assembling blocks, wherein a conical protrusion is also mounted on one side of each of the concrete block assembling blocks, a fixing foot is arranged at the bottom of each of the conical protrusions, each of the fixing foot is fixed to the corresponding concrete block assembling block, and a conical dent is formed in the other side of each concrete block assembling block; the size of the conical dents is consistent with that of the conical protrusions; the concrete block assembling blocks are made from frost-resistant concrete to which modified nanometer material namely vanadium pentoxide is added. Through the assembled concrete road provided by the invention, quick assembling and paving can be realized, and the assembled concrete road has good shear-resisting effect.

Description

Technical field [0001] The invention relates to an assembled concrete road. Background technique [0002] At present, a large number of roads of various grades are built in the society, and a large part of them are concrete roads. At present, domestic concrete roads mainly use cast-in-place concrete construction technology, which requires on-site support formwork, lashing of steel bars, concrete pouring, and concrete maintenance. The main disadvantages of the cast-in-place concrete production process are as follows: [0003] The production efficiency is low, it consumes a lot of human resources, and the construction period is long. On-site construction mainly uses manual operations, and product quality is not easy to guarantee. Great environmental pollution, noise, sewage, waste and other environmental pollution caused by concrete pouring on site. When the pavement is demolished or abandoned, the pavement materials form construction waste, which cannot be reused, resulting in a...
