Eco Material has reengineered pozzolanic cement to make it react faster—matching the one-day performance of portland cement. PozzoSlag? can replace a significant portion of the portland cement required to make high-strength, durable concrete. It is 20% stronger than portland cement in 28 days and continues to gain long-term strength. Moreover, PozzoSlag? can be made at room temperature with virtually no emissions—a near-zero-carbon cement.
