we have an immense pleasure to introduce ourselves as the best and leading manufacturer, exporter and supplier of the following from our own mining. We are having huge production as well as storage capacity at our plant. ► standard sand grade- I ► standard sand grade- ii ► standard sand grade- iii ► all grade silica sand you wil be glad to learn that, all the gradations of standard sand are as per the b I s and we will be giving a test report of our own laboratory. We are pleased to announce the brand name of our standard sand which is quartzanium ™ quartzanium ™ is the indian standard sand as per is-650: 1991 of b I s, to be used to various cement plants, research laboratories, civil engineering institutions to ensure the quality of cement. One can recognize quartzanium ™ as amongs either of quartz, quartzite or silica the best standard sand. Quartzanium ™ has passed all the parameters set by b I s. Quartzanium ™ can be proven for following standards. ♣ physical properties ♣ chemical properties ♣ petrography analysis ♣ compressive strength for the satisfaction and surety please find attached the technical comparatives. We will be proud of associating with you and will be waiting for your valuable response as well as suggestion after using our samples which we are sending here with [ 200 grams of each grade ].
