With our mobile nitrogen pumping equipment, Linde Services Inc. has the ability to provide a turnkey concrete-cooling service on-site at almost any location with proven reliability critical to any concrete-cooling operations. Traditional liquid nitrogen cooling systems require a permanent or semi-permanent cement base to anchor injection arms.
Site surveys can be conducted to ensure you have the correct mixing or pumping solution in the short, medium and long-term: Audit of your site systems. Specification …
For 3DCP operation, especially with the long pumping stage, the main hydration peak occurrence must be delayed to avoid setting in pumping pipes. This is generally achieved by using set-retarders. On the other hand, once the material reaches the print-head, the composition is adjusted to obtain faster hydration.
Computation of mixing ratios is illustrated in Fig. 1 when two sources of recharge exist. Assuming conservative species, the concentrations C1, C2 of a mixture are linear combinations of those of the end-members with coeﬃcients given by the mixing ratios. 25
When ready-mixed concrete is furnished, the contractor shall furnish the engineer a delivery ticket showing the time of loading and the quantities of materials used for each load of concrete. Concrete shall be placed within 1.5 hours after introduction of the cement to the aggregates or within 45 minutes when the temperature of the concrete is 85 degrees Fahrenheit or greater.

Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes —a pipeline—typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than 2,175,000 miles (3,500,000 km) of pipeline in 120 countries of the world. The United States had 65%, Russia had 8%, and
Our tile adhesive mixing machine can be equipped with single-stage linear vibrating screen, also classifying screen. As for how to choose right screen system? You can according to the sand, if you use general river sand, and without crusher device, linear vibrating screen is enough; if you use mountain flour, you'd better choose rotary screen.
Technical note 2012/08 6 Sterilisation of the well was achieved by adding chlorine to the drilling fluid and maintaining this throughout the drilling process. The well is artesian with a head calculated at 0.5 m above ground level. An airlift yield of 60 L/s was estimated

We can provide liquid nitrogen for your most challenging concrete cooling requirements, temperature specifications during high heat conditions, and other pour jobs in need of concrete cooling, such as caps and columns, bridge decks and power plants have all been poured using liquid nitrogen.
14/12/2015 · Additionally, the screen 290 also shows the total/stage volume 294 being pumped during the job, as well as the downhole pumping rate 296, which remains constant throughout the job. Similarly, FIG. 21 shows an output interface screen 298 for a pumping operation utilizing a decreasing ramped injection rate 300 .
25/1/2021 · After curing, concrete starts to deform with environmental influences; thus, shrinkage is influenced by external supply water, so the climate plays an important role. Because the hydration process may occur for a long time, shrinkage occurs simultaneously with hydration, causing the shrinkage mechanism to become complex.
