Climatic chamber for building materials climatic testing

Flooding test chamber for EN 1367-1

Materials tend to change their characteristics according to the different environmental conditions to which they are exposed.


Starting from the nature of each and the use that will be made of them, it is essential to be able to foresee the reaction of a compound in any possible situation, before putting it on the market.

The topic gets even more important when we talk about building materials.

The compounds used to build our homes and buildings, must be subjected to more stress than others and to reproductions of environmental conditions that simulate real ones:


we are talking about climatic tests for building materials.


Global warming and building materials


Today, more than ever, buildings have to deal with the consequences of global warming, a key topic in many recent debates.


Buildings, especially those who are not recent designed, have shown a significant increase in damage in recent years. The unpredictability of weather conditions (droughts, rains and strong winds, record temperatures – see the urban heat island phenomenon) is seriously endangering our buildings.


An unmanageable vulnerability, if we do not do anything to solve the issue.


The unraveling of structures due to the effects of climate change is an increasing phenomenon: one of the various examples we have already discussed is that of Frost heaving

So how do we build buildings that are less subject to these unpredictability?


Subjecting building materials to stability tests and accelerated aging tests


The growing demand for more resistant, flexible and less exposed building materials to the various climatic phenomena has consequently increased the demand for more rigid tests on construction materials.


At the same time, the various research laboratories have developed regulations and reference standards to officialize the various processes.


The most common reference standards are: EN-1367-1, EN-12004; EN-1348


How to produce resistant building materials then? By subjecting materials to climatic tests.


FDM – Environment Makers


FDM is in the field since 1949: over the years we have acquired a unique know-how, and have become a leader in the field of materials climate testing, thanks to a focus on innovation and customers’ needs.


As for the latter, in fact FDM can provide full customized solutions, even from scratch, based on the customer’s different requirements, starting from the core business, that of the climatic chambers.


Concrete testing in a climatic controlled environment


Let us consider the specific case of concrete.


Several companies contact us every day to perform climatic chamber test for specimens / samples of building materials such as concrete.


The problem to be solved is to test concrete resistance to different environmental conditions.

The FDM flooding climate chamber system


To perform concrete tests in a climatized environment, we have created a controlled environment with a flooding system.


The climate chamber equipped with the FDM flooding system for tests on building materials treats the concrete by immersing it in water and controlling it climatically through a system of tanks.


The tanks system for climatic chambers, allows to fill and empty water in a container located inside the climatic chamber, without having to open it.


It is composed of two containers of 150 liters each.

Water tank for flooding test

The filling of the inner container is managed by a level device.

Water filling and draining takes place via a fill / drain valve located at the bottom of both containers.

The external container is divided into two parts, one contains the water and the other one manages its movement.

Inside a hydraulic pump, a drain valve and a temperature thermostat for water are installed

The thermostat is set at 23° C by the manufacturer, and manages the exact water temperature through a resistance.
