Raw Materials For Concrete Blocks And What Each One Changes
Sand, stone, cement, fly ash, slag, coal gangue and construction waste all appear in the published material lists. They do not behave the same way.
What The Machines Are Specified To Take
The QT4-15 specification lists sand, stone, cement, fly ash, slag, coal gangue and construction waste. The QT5-15 lists fly ash, slag, gangue and other industrial waste alongside river sand, gravel and cement. The QT10-15 lists cement, river sand, fly ash, slag and recycled construction waste. In every case cement is the binder and everything else is aggregate or filler.
Industrial Waste As Aggregate
Fly ash, slag and coal gangue are attractive because they are cheap or free and because using them supports green production policy. They also vary far more than quarried aggregate, which is why block quality on a waste-fed line needs the dosing and distribution control that the automatic machines provide.
Construction Waste Needs Processing First
Recycled construction waste has to be crushed and graded before it behaves like aggregate. Once it does, it is listed as a valid feedstock on the QT4-15 and the QT10-15, which is what makes on-site recycling of demolition material into blocks practical rather than theoretical.
Prove The Mix Before Buying The Machine
Clients may send raw aggregate to the Linyi factory for free moulding tests. What comes back is finished block samples, test videos and a production parameter report for the block production line. That is the only reliable way to know how your local material behaves before capital is committed.
