According to Mining News Pro - “We now work to prohibit the import of poor-quality cement. The quality is shown by the drying of the product in less than 30 days, but Peruvian cement has a poorer quality, which is why works are cracked. This cannot be allowed to happen and therefore, we are addressing this through a standard,” he explained.
"We are giving a deadline (to the industries) because they have stock to sell in the year and from July we will start the uniform control of cement and good-quality cement will enter the country,” said Mr Rojas.
