What
you need to know before building a wall: First step of laying
a foundation is deciding on the material and size of the blocks you will use.
Cement blocks (or cinderblocks) are becoming more popular as they require less
time and effort to build with than bricks or stones. Once set into place,
cement block walls provide great support and enough space for a small home
addition year down the road. Cement blocks are incredibly strong, but you need
to choose the right ones for your project.
There
are many different Cement Block Manufacturer in Mumbai that produce cement
blocks, each using its own design and mixture of materials. Knowing which
company made your block is not as important as knowing what type of cement was
used. Plastic and rubber additives were regularly added to cement from the
1950s on, with most manufacturers (and most countries) halting production in
the early 70s when they began to realize that these chemicals posed a serious
health risk.
There
are three basic types of cement blocksprovide by the Cement
Block Manufacturer in Mumbai:
Plastic-bonded
—
These were the most common type of cement block. Manufacturers used additives
called "plasticizers" to extend their cement supply and reduce the
amount of limestone used in production, a major component of cement.
Unfortunately, plasticizers have been shown to cause cancer, so you can no
longer find this type of block being sold.
Fly
ash — Cement (and cement block) manufacturers typically
use chemical additives (fly ash, slag, silica fume) to strengthen their
product. Fly ash is an industrial waste containing low levels of heavy metals
that can be harmful if inhaled or ingested over time. Most new cinder blocks
available today are made with fly ash rather than (or in addition to) chemical
additives.
Portland
cement — This is the purest type of block, the one with no
significant health risks. Just be aware that it can burn your skin and irritate
your eyes if not treated carefully during installation.
