METHOD FOR ADHERING TO FRESH CONCRETE TEMPERATURES
Method and installation (100) for providing a batch of fresh concrete having a temperature in a predetermined temperature range at a remote point of use, whereby a control unit (140) controls at least one step of cooling of cement and/or aggregate and/or mixing water before mixing and/or of the fresh concrete, during the production of the batch.
Solvent management methods for gel production
Embodiments of the present invention describe a method for manufacture of a gel material comprising the steps of: forming a gel sheet by dispensing a gel precursor mixture; allowing gelation to occur to the gel precursor mixture; and cooling the formed gel with a cooling system to control reaction rate.
Method for preparing hot-mixed asphalt mixture
The present invention provides a method for preparing a hot-mixed asphalt mixture, and relates to the technical field of road engineering. In the present invention, asphalt and aggregates are preheated separately, where the aggregates include coarse aggregates and fine aggregates; the coarse aggregates, part of the fine aggregates and asphalt that are preheated are subjected to a first mixing to obtain a first mixture; the remaining fine aggregates are added to the first mixture for a second mixing to obtain a second mixture; and a mineral powder is added to the second mixture for a third mixing, and discharging is conducted to obtain a hot-mixed asphalt mixture.

CERAMIC SANITARY ARTICLE AND METHOD FOR PRODUCING SAME
A method for producing a ceramic sanitary article, more particularly a washbasin or washstand, wherein a mold is used to produce, from a ceramic composition, a green body, which is subsequently fired in a firing to form a fired body, where the fired body after the firing is subjected to material-removing working on one or more visible faces until it has a desired dimension, after which the worked body is glazed at least on the worked visible face or faces and is fired a further time in order to fire the glaze.
DEVICE AND PROCEDURE FOR COOLING FRESH CONCRETE AT ELEVATED TEMPERATURES
The device and procedure for cooling fresh concrete at elevated temperatures enable efficient cooling of fresh concrete, which is achieved by the subject device comprising of: cooling station (1) with measuring and regulating equipment (2) and safety equipment (3), solenoid valves (5), pressure transmitter (6), cryogenic shut-off valves (7), collector (17) made of stainless steel pipes with temperature probes (8), concrete mixer (9) and manometer (10) with safety valves (11).
The procedure of cooling fresh concrete using liquid nitrogen in the mixer is carried out as follows: first aggregate-separated gravel is added, then cement, then water and finally, if necessary, additives-chemical additives. Mixing of added raw materials lasts from 15-20 seconds, until a homogeneous mixture is obtained, after which liquid nitrogen is added at a pressure of 6 bar, giving cooled fresh concrete on which no surface cracks and fissures appear at external temperatures of 30-35 C.
PREDETERMINED TEMPERATURE PROFILE CONTROLLED CONCRETE CURING CONTAINER
The invention comprises a method of curing concrete. The method comprises placing a concrete cylinder in an insulated container having a sufficient quantity of water therein so that the concrete cylinder is submerged in and surrounded by the water and selectively adding heat to the quantity of water in an insulated container, so that the temperature of the quantity of water follows a predetermined temperature profile.
