# 25 Mpa Concrete To Psi

25 mpa, 30 mpa, 35 mpa or 40 mpa - basalite,25 mpa, 30 mpa, 35 mpa or 40 mpa description: concrete mix is a pre-blended mix of fine and coarse aggregate and type 10 portland cement packaged in 30 kg sacks and in one cubic yard (.76 m3) bulk bags. concrete mix is a quality, pre-blended high strength concrete mix suitable for any concrete repair or new concrete construction. the material requires only the addition of water..how many bags of cement are required for 20 mpa concrete,mpa is megapascal, 1 million newtons per square meter. so 20 mpa concrete isn’t determined by number of cement bags but mix ratio of portland cement to water and aggregate and followup hydration. the mpa mix ratios, fairly standard all over, are a....

• ### Convert 25 MPa To Psi - UnitConversion.io

to convert megapascals (mpa) to pounds per square inch (psi), you just need to know that 1mpa is equal to 145.04 psi. with that knowledge, you can solve any other similar conversion problem by multiplying the number of megapascals (mpa) by 145.04. for example, 2 mpa multiplied by 145.04 is equal to 290.08 psi.
