CONCRETE BLOCK HAVING A COLOR WHICH CHANGES DUE TO TEMPERATURE AND HAVING DIFFERENT COLORS AT THE SAME TEMPERATURE BY MORE THAN TWO THERMOCHROMIC PIGMENTS

摘要

PURPOSE: A concrete block having a color which changes due to temperature is provided to detect the temperature of a road surface for itself and visually change a color due to the change of temperature.;CONSTITUTION: A manufacturing process for a concrete block(1) having a color which changes due to temperature comprises the steps of: mixing an existing concrete(3) and mortar which is mixed with cement, water, and fine sand; adding thermochromic pigment(5) of about from 1 to 30 percent of total weight; filling a prepared mold with the mortar to maintain a whole shape; molding by evenly compacting through pressurization and vibration; drying and hardening; and making a complete block by removing the mold after curing.;COPYRIGHT KIPO 2013
