DurableFamed Roman structures, such as the Pantheon, Colosseum and aqueducts, are still

standing today. One secret to the long-term durability of these structures is that the

Roman builders turned to volcanic ash to harness the power of pozzolans. Like Roman

concrete, fl y ash pozzolans in the chemically-balanced formulas of Magna Wall™

masonry cement react to free lime, forming additional cement binder. This leads to

greater durability of the Magna Wall™ masonry cements.

product Overview

Magna Wall™ Mason’s Portland Cement 1P is the “green” equivalent to ASTM C150 Type I Cement.

Basic Use:

Magna Wall™ Mason’s Portland Cement 1P is an ASTM C595 Type IP cement (Type I cement with pozzolan addition) and also can be classifi ed as an ASTM C1157 Type GU cement (General Use). It can be used wherever Type IP cements or GU cements are specifi ed or authorized. It is an excellent choice for making cement/lime mortars and stuccos on the job-site. Each year, more standards requiring ASTM C150 Type I portland cement recognize Type IP cements as an acceptable alternative.

A Green, User Friendly Portland Cement 1P

By using fl y ash, this Portland cement 1P is one of the greenest Portland cement materials available. While this would be enough to justify using this product, it carries with it several additional benefi ts. When Portland cement hydrates, very fi ne particles of hydrated lime are given off. Often as much as 20% to 25% of the weight of the Portland cement is given off in the form of fi ne hydrated lime. Since the pozzolan combines with the lime, the amount of lime available to migrate to the surface and cause effl orescence is reduced. When the lime and the pozzolan combine, they form additional cement binder, which leads to greater strength. This strength gain can continue for an extended period of time.

Composition and Materials:A blend of portland cement and high performance pozzolan.

Bag Weight: 94 pound bags (42.7kg)

Color: Gray

Storage: Store in dry area off the ground.

Shelf life: Approximately 6 months.

General Guidance - Mixing and Application:• Do not add air-entraining agents, mortar fat, antifreeze, accelerators, or

waterproofi ng agents, as they may interfere with the chemical integrity of this product.

• Do not use as mortar, stucco or concrete at temperatures below 35°F, or when freezing temperatures are anticipated within 24 hours.

• Follow traditional guidelines for curing.

Magna Wall™ Mason’s Portland Cement 1P

product instructions

A. General:Magna Wall™ Mason’s Portland Cement 1P is designed to be used wherever portland cement Type I is utilized. Magna Wall™ Mason’s Portland Cement 1P is available only in bags, thus it is not practical to use in ready-mix applications.

B. As a Mortar or Stucco:Magna Wall™ Mason’s Portland Cement 1P is especially useful for job-site mixing of mortars and stuccos because the spherical shape of the pozzolan particles leads to increased workability. The major differences that tradesmen will notice will be the increased workability with less mixing water. Following are suggested starting formulas:

Type N Mortar1 bag MW Mason’s Portland Cement 1P0.5 bag of hydrated lime4.5 cubic feet of masonry sand

Type S Mortar1 bag MW Mason’s Portland Cement 1P0.25 bag of hydrated lime3.75 cubic feet of masonry sand

Scratch Coat Stucco1 bag MW Mason’s Portland Cement 1P0.5 bag of hydrated lime3.75 to 6 cubic feet of plaster sand

C. For Concrete Work:Magna Wall™ Mason’s Portland Cement 1P gives the advantages of pozzolan incorporation to small concrete pours. These advantages includereduced bleeding and segregation, more impervious concrete, reduced expansion resulting from alkali aggregate reaction,and continued strength gain over time.
