Published by YTL Cement Marketing Sdn BhdCopyright @ YTL Cement Marketing Sdn BhdPublished @ November 2010

MASCEM is certified to MS 1227 : 2003 Specification for Portland-fly ash cement (fly ash content 6 – 35%). MASCEM also conforms to CEM II/B-V of MS 522-1 : 2007 (EN 197-1 : 2000).

CERTIFICATIONS

MASCEM is suitable for applications in marine environment, mass concreting, sulfate environment, water retaining structures, basement and other structures which require low heat of hydration.

APPLICATIONS

PROPERTIES

MASCEM is produced using the most advanced energy efficient cement production process. The use of high quality fly ash to replace a portion of the clinker served to reduce significantly the total embodied CO2/ton of the product. Every ton of fly ash used to replace clinker saves around 900kg of CO2 being released into the environment and this makes MASCEM a more sustainable cement.

ENVIRONMENTAL BENEFITS

MASCEM is available in bulk from YTL Westport cement plant.

AVAILABILITY

MASCEM is produced under stringent quality assurance, environmental management and health & safety systems. It is certified to MS ISO 9001, MS ISO 14001 & OHSAS 18001.

QUALITY ASSURANCE

MASCEM is the trade name of a specially manufactured Portland-fly ash cement produced by blending good quality fly ash with Ordinary Portland Cement (CEM I).

MASCEM PORTLAND-FLY ASH CEMENT (CEM II/B-V)

Cement is classified as an irritant and direct contact with the skin should be avoided. It is recommended to use Personal Protective Equipments which include eye, hand, skin protection and dust masks. First aid treatment should involve the immediate bathing of the affected area with water.

TESTINGMS ISO/IEC 17025

ACCREDITED LABORATORY

The UK Building Research Establishment (BRE) Digest 363 : 1996 and BS 5328 : Part 1 : 1997 have recommended the use of high PFA content cement (> 25% by mass of combinations) be extended to the most severe Class ‘4’ and Class ‘5’ sulfate conditions.

HIGHER RESISTANCE TO SULFATE ATTACKS

Slower initial hydration of fly ash reduces the risk of thermal cracking with lower peak temperature and temperature differential.

Lower temperature rise will reduce the risk of early age thermal cracking in concrete.

LOWER HEAT OF HYDRATION

MASCEM reduces risk of damage and expansion caused by alkali-silica reaction. Recommendations and guidelines are given in BS 5328 : Part 1 : 1997, UK Concrete Society Technical Report No. 30 (1995) and BRE Digest 330 : 1997.

1. C, to accommodate fixing precision (nominally at 10mm)

2. For nominal cover of 40mm + C, OPC concrete is not allowed. MASCEM with 21% to 35% fly ash (Group 5) is the preferred cement type over OPC for marine structures in XS3 exposure class

3. XS3 = Tidal, splash and spray zones

1. For sulfate resistance, cement in group 1 (OPC) is deemed to be least preferred, followed by cement in group 2a, 2b & 3 respectively. MASCEM with 30% fly ash (Group 2a) is a preferred substitute for OPC (Group 1) in sulfate resistance
