Ground limestone
Ground limestone for concrete mixes VBS 40/V
Ground limestone VBS 40 is produced by grinding natural limestone to the required fineness.
Area Of Use
Due to its high chemical purity and granulometry, it is particularly suitable for the preparation of concrete mixes in concrete plants or for the production of dry gypsum.
