  • Explanation
Aggregates
Aggregate is a material such as gravel or sand that is used in making concrete. Concrete is made by mixing cement, aggregate and water. Mitsubishi Materials also sells limestone, copper slag and other materials as aggregates.
Blast Furnace Slag
Of the iron and steel slag generated during steelmaking, this slag is the result of pig iron smelting in a blast furnace. This slag contains large amounts of silica and calcia, so in addition as a cement ingredient it is used as an aggregate in blast-furnace cement.
Cement Milk, Cement Paste
These mixtures of cement and water are called milk or paste depending on the amount of water they contain. They are used for repairing cracks and other applications requiring greater fluidity than mortar.
Cement Transportation Truck
This refers to a truck used to transport cement that is not bagged.
Clinker
Clinker refers to the lumps measuring around 1cm in diameter that form as a result of rapid cooling following the mixing of cement materials and high-temperature firing. Clinker is crushed further and mixed with plaster to make cement.
Controlled Soil
This type of surplus excavation soil has been subjected to soil or radioactive contamination and therefore cannot be disposed of outdoors as is.
Cubic Yards
This refers to one yard cubed, in Imperial units. One cubic yard is equivalent to 27 cubic feet or precisely 0.764554857984 cubic meter.*
Fine Crushed Limestone
This sand, which results from finely crushing limestone, is chiefly used as an aggregate. It has strength comparable with natural sand and does not cause an alkali-aggregate reaction, which can result in fissures.
Fly-Ash
This type of ash is generated when coal is incinerated. Spherical and with fine particles, when mixed with cement fly ash increases its fluidity. Fly ash is a JIS-standard industrial product.*
Geothermal Well Cement
This type of cement is even more resistant to high temperatures than oil well cement. It is used for wells at geothermal power stations that produce hot water and steam.
Grouting Mortar
Grout is a fluid mortar injected to fill in cavities, voids, crevices and other spaces.*
Heat of Hydration
This is the heat generated during the hydration reaction between water and cement.*
High-Early-Strength Portland Cement
This cement develops strength earlier than standard cement and is used to shorten construction times.
Mixer Truck
A mixer truck is a truck for transporting ready-mixed concrete.
Mortar
Mortar is a mixture of cement, sand and water used to finish wall exteriors, joints, etc.
Oil Well Cement
This type of cement is for use deep underground in extremely harsh high-temperature, high-pressure environments such as in drilling oil and gas wells.
Ordinary Portland Cement
This refers to standard Portland cement. Regulated by JIS, this is a highly general-purpose cement that can be obtained anywhere in Japan.
Portland Blast Furnace Slag Cement
This cement contains a mixture of finely powdered blast-furnace slag. It offers excellent chemical resistance and continues to grow in strength over a long period of time.
Pre-Heater, Suspension Pre-Heater
A preheating device located at the pre-stage of a cement firing kiln, a preheater uses kiln exhaust gases to calcinate cement up to 900°C. This approach results in substantial energy savings compared with injecting materials directly into the kiln.
Pre-Stressed Concrete
Refer to PS.
PS
PS is an acronym for pre-stressed. With pre-stressed concrete, when making concrete slabs tensile stress is applied to the rebar at the factory in advance. After the external load is removed the residual tensile stress in the rebar acts as a compressive stress on the concrete. This reaction results in higher flexural strength. Pre-stressed concrete is used in bridges and beams, pilings, utility poles and other applications.
Ready-Mixed Concrete
In ready-mixed concrete, cement, sand, crushed stone and water are mixed in prescribed ratios. The hydration reaction begins immediately after mixing, generating heat. This type of concrete must be used within 90 minutes of mixing.
Service Station
Bulk cement that has been produced at a factory is hauled by tanker, railroad freight car or tanker truck to a service station, where it is temporarily stored in silos. From this facility, cement is transported to customers in bulk or packaged into sacks, according to demand.*
Short Tons
This refers to a U.S. ton, in Imperial units. One U.S. ton (short ton) equals 2,000 pounds, equivalent to approximately 907.2 kg in metric units. One U.K. ton (long ton) is equivalent to 1,016kg.
Slag Aggregates
This concrete aggregate is obtained by crushing and adjusting the particle size of the slag generated as a by-product of metal smelting. Used as a substitute for natural aggregate, for which collection is restricted, slag aggregate is an industrial product with standardized constituents and particle size.
Soil Stabilizing Cement
This material is used to improve weak ground that does not have sufficient proof strength for a building foundation. Mitsubishi Materials provides cement-based soil improvement solidifying material.
Sulfate-Resistant Portland Cement
This cement, in which the aluminate phase is as small as possible, is highly resistant to sulfates, which can be found in seawater, on ground near hot springs, or in locations that may include sewage or industrial wastewater.
Terminal
In the cement business, this refers to an import terminal, a site for relay shipment of cement.
Waste Gypsum Board
This refers to gypsum board generated as waste when buildings and other structures are dismantled.
