How is a spark-free floor made?

We do have one like this in our workshop; we didn’t pay attention during the construction in 2012 and thought it was just an ordinary concrete floor. Later, upon learning that it was a ground surface that did not ignite, I asked the construction party, but I didn’t get a clear answer; it seems that the formula for the concrete is different.

For methods of creating non-sparking floors, refer to 05J909

There are guidelines for non-flammable flooring, but the actual materials are difficult to obtain and pose challenges in terms of procurement. There is now a powder that can be evenly spread on the concrete floor before it has fully set, after which the floor can be leveled and polished.

The construction method is similar to that of ordinary floors, mainly involving the use of non-sparking materials

Where can I buy the spark-free ground powder?

There are several types of non-sparking floors, such as non-sparking fine aggregate concrete surfaces, non-sparking cement mortar surfaces, non-sparking asphalt mortar surfaces, non-sparking epoxy mortar surfaces, and other such floors. The relevant codes include \"GB 50037-2013 Code for Design of Building Floors\" and \"GB 50209-2010 Code for Acceptance of Construction Quality of Building Floor Works\". The main reference manuals involved include \"05J909 Construction Practices\", \"14J938 Building Constructions for Blast-Resistant and Blast-Venting Doors, Windows, Roofs, and Walls\", and \"12J304 Building Constructions for Floors and Ground Surfaces\". Take the commonly used non-sparking fine aggregate concrete finish as an example; a common practice is as follows: First, the aggregate (i.e., fine aggregate) is replaced with limestone or dolomite that meet the non-sparking requirements, and the construction method remains the same as that for ordinary fine aggregate concrete. II. After pouring the fine aggregate concrete, scatter aggregates on it both horizontally and vertically; polish it as it cures, and apply a second layer once it has set slightly. III. When purchasing ready-mixed fine aggregate concrete for use in self-construction, it is important to note that such products contain various cement additives, which result in high viscosity; they tend to develop cracks upon initial setting, and require proper curing. If one lacks construction experience, it is advisable to have guidance available. IV. Go directly to the cement mixing plant to purchase non-sparking fine aggregate concrete for construction.

1. Not all Class A areas require non-sparking flooring; such flooring is only necessary for indoor floors where flammable gases heavier than air are present. 2. There are guidelines available regarding the method of implementation, which mainly involves using fine aggregate concrete mixed with dolomite or limestone
