In industrial facilities, conventional weight concrete, lightweight concrete, and intumescent fireproofing are the three main passive fireproofing technologies used. Depending on the environment the structure is in, the function of the structure, its anticipated lifespan, and the level of long-term maintenance commitment, each system can be employed successfully and affordably. Now is your time to find me a fire proofer in Sydney.
It is less common than normal weight fireproofing and typically weighs less than 75 pounds per cubic foot. Lightweight concrete fireproofing is a commercially accessible product. Its main benefits include being easier to apply with spray or trowel methods being the most popular, being lighter weight, having stronger thermal resistance than regular weight concrete, and being less weight.
However, the material is porous, making it simple for moisture to reach the steel beneath, thus careful thought must go into where it is used. Durability issues may arise because it frequently lacks standard weight concrete’s impact resistance. Due to these drawbacks, it may only be utilised in certain situations and needs more frequent, expensive maintenance.
Although it has a distinct mix design, normal weight concrete fireproofing is comparable to concrete used for structural applications. By passivation the steel, it has the benefit of being the most protective fireproofing for the underlying structural steel.
Additionally, it is widely accessible, robust, long-lasting, and simple to maintain, and many craftsmen are familiar with it and its use. The main drawback of regular-weight concrete is its weight.
