Degrade and fail

Concrete can present various degradation problems which reduce its durability and resistance. The main ones are:

–descaling with loss of lime by hydrolysis, consequent increase in capillary voids, predisposition for cracking along the reinforcements and reduction of mechanical strength

–sulphatic attack of magnesium which produces swelling;

–carbonation which leads to the formation of calcium bicarbonate with lower characteristics than the original matrix;

By means of a specific electrochemical process an anodic reduction takes place and a consequent cathodic deposit of rust with reduction of the useful section of the reinforcement and formation of swelling of the concrete (spalling).

PROBLEMS: superficial detachments, swellings, cracks and cracks

SURVEY TECHNIQUES:  corrosion analysis

Hardy slabs can present important mechanical resistance problems.

PROBLEMS: deformations and subsidence

SURVEY TECHNIQUES: sonic analysis, endoscopy, load tests, pacometers

all masonry and reinforced concrete structures can present injuries due to thermal, static and dynamic phenomena.

PROBLEMS: surface injuries, detachments, infiltrations

SURVEY TECHNIQUES: CONCRETEcrack pattern analysis, deformometry, thermal monitoring

Buildings and structures can present problems of waterproofing or disposal of rainwater.

PROBLEMS:humidity, spots

SURVEY TECHINIQUES: thermography, surface and internal temperature and humidity measurements

The thermal insulation characteristics of buildings represent the fundamental component for the realization of living comfort.

PROBLEMS: energy consumption, humidity, stains

SURVEY TECHNIQUES:
thermography, surface and internal temperature and humidity measurements

L’incendio, nel caso delle strutture in cemento armato, può portare ad una riduzione non immediatamente evidente della sua resistenza meccanica. 

PROBLEMI: distacchi, riduzione capacità portante

TECNICHE DI INDAGINE: sclerometria, analisi sonica, microscopio ottico
