After that, various professional tests on uniformity, impermeability and frost resistance are provided to illustrate the performance of the colored concrete.
One is the uniformity of the color in other kind of ambient medium, such as water, and the other one is the uniformity of the same concrete with different color.
Considering the first situation, we submerge a colored sample block in the water in 7 days.
And after 7 days submerging, the water is still crystal and the sample does not fade.
The impermeability is the resistance performance of the concrete by the penetration of water and oil.

The anti-floating structure checking and impact of changes of groundwater characteristics, water pressure and buoyancy and groundwater level are related to the water replenishment.
For these problems which have serious impact on building’s life and even the human life safety with the fluidity of water.
For roads, the site testing during the laying and the roadbed stability will be affected by water.
For the bridge, because of its special nature of the built environment, water impact is its major problem.
The sustainability of water is persistent destruction for the piers, which is inevitable, especially in rain-fed areas.

For the ecological function of the vertical green garden, environmental professionals research more.
One of the characteristics of ‘virtual-shape’ vertical interface is that it can make the material shade diversification, plant, water, mirror and wood subjects are all the major elements of virtual-shape interface.
The fresh plants is full of life, and the brooklet make water moving like, these are all the condiment between people, hard-material space and interface.

(1) Environmental monitoring includes the monitoring for the upstream and downstream water level of the dam, water temperature of reservoir, air temperature, sedimentation in front of dams, downstream erosion and deposition
(4) Stress-strain and temperature monitoring includes the monitoring of concrete stress, strain, steel stress, steel plate stress of the steel pipe and volute, concrete temperature, foundation temperature, void water pressure in embankment dams, earth pressure (stress) force, etc
To obtain a more accurate result, a fine division could be conducted for the upstream water level interval.
This software can be used for small and medium-sized dam safety monitoring information management, and the original manual processing by the professionals in data analysis and preparation of reports now is fully completed by a computer system, greatly improving the work efficiency, saving enormous human and material resources.

The construction process is: basic layer test the water - base layer - zoning - plastic underlying laying - plastic surface spray - process line.
The Surface Layer Construction Methods Comply with the rules promulgated by the IAAF requirements in order to ensure the quality and flatness of the polyurethane runway surface layer of pavement, slope, and at the same time to ensure the quality and perception of the future use of plastic track, before the plastic surface pavement acceptance must be the quality of the original foundation, concrete Standard reference the IAAF standard manual and design drawings of the venue provisions of the indicators, its procedures are as follows: Grassroots Acceptance and Problem Rectification Collection of the original raw materials used in foundation construction quality inspection report, inspection report of the coefficient of thermal stability and density of two indicators; -site measurement of the flatness of the original base layer, slope; elevation and the control of water level detection axis references point relative elevation, and whether international IAAF manual requirements, identify
In order to ensure the entire site pavement smooth, uniform thickness, watered with tap water on the entire site before construction, watering should be thorough and Slow Note overland flow, non strong red pen well marked depression hydrocephalus at material polyurethane bottom reinforcing.
All management and operating team will strengthen the sense of quality and quality functions; implementation of the responsibility engineers and professional quality control engineers responsible for system and comprehensive management and control of the quality of the project, the whole construction process; through a clear division of labor the person in charge of the construction unit project supervision engineers and construction side of the close coordination and cooperation, the effective control of the quality of the project.
The Quality Control Measures In construction, engineering construction section, the various types of work, between the professional staff closely with the construction, each division of a unified governing staff work by the project manager should work together to completion of works on time and durability.

Such environmental influences include water, greases, oils, chemicals products for coatings, road salts, spilled fuel and other automotive fluids.
The polyamide 12, in addition to the characteristics mentioned above, has low water absorption, allowing their physical properties to remain effectively stable under humidity, and excellent abrasion resistance, which enables to support the friction which may occur under the vehicle [5, 6, 7].
The International Society of Automotive Engineers (SAE) coordinates the development of technical standards based on best practices, identified and described by engineering professionals from relevant fields.
The first test method requests to immerse the samples in a 50% aqueous solution of zinc chloride for 200 hours at 23 °C and the second one asks for 50% engine degreaser and 50% water for 60 days.
The fluid agent Solupan was diluted in water at concentrations of 15:1 and 30:1 (volume fractions of 3% and 6%).

Water absorption was conducted by weighing the samples of paving stones after 28 days of curing.
The samples were then immersed in water for 24 hours and the new weights of each sample measured.
Effects of the CSA on the compressive strength of the interlocking paving stone Water Absorption Fig. 6 presents the effects of CSA percentage replacement on the water absorption rate of the interlocking paving stone.
