The present invention relates to a crystalline growth-type concrete-mixing powdered spherical waterproof agent having an improved autonomous healing function. After cement, silica, crystalline quartz, and cryptocrystalline quartz are combined, quartz, talc, and zinc stearate which are heated at a high temperature are mixed. According to the present invention, when cracks occurs in concrete, penetrated water and particles of cement are reacted to produce a deformed calcium silicate hydrate and fill cracks. Moreover, a composite catalyst generated when being reacted with water is promoted to continuously produce a deformed calcium silicate hydrate, so autonomous healing can be permanently ensured when cracks occur in concrete and strength of concrete is improved. Moreover, crystalline quartz is more combined than cryptocrystalline quartz, and heating is performed at a temperature increasing speed of 15-25°C/min. Then, clacining is performed, so a waterproof agent having more excellent strength ...

The present invention relates to an apparatus to control the melting of an ingot and a method thereof. According to the present invention, the apparatus comprises: a plating tub unit which accommodates a plating solution; a storage unit which has an accommodation space with a top surface open, into which an ingot is put, to put a plating solution in the accommodation space when the storage unit is sunk in the plating solution of the plating tub unit, thereby melting the ingot; and a discharge unit connected to one or more surfaces of the storage unit to discharge the plating solution in the accommodation space to the outside of the accommodation space and to supply the plating solution to the plating tub unit. When the discharge unit discharges the plating solution in the accommodation space to the outside of the accommodation space, the plating solution in the plating tub unit is brought into the accommodation space. According to the present invention, the method comprises: (a) a step ...
