Building Materials Lab

  1. The Materials Testing Laboratory of P&P LMC srl is an Official Laboratory pursuant to Law 1086/71 art. 20 and D.P.R. 380/01 art. 59.

The Official Laboratory is authorized by the Superior Council of Public Works to carry out tests on concrete cubes and reinforcing bars for the issue of official Certificates valid for the testing of the structures; with the new Technical Regulations referred to in the D.M. 17.01.2018, also the sampling from the structures (cores and extraction of bars) and the compression and traction tests, for the evaluation of existing buildings, must be carried out by an Official Laboratory.

The Materials Testing Laboratory performs tests for the CE marking of construction materials, according to the CPR 305/11 regulation and in accordance with the relative harmonized product standards

The activities of the Laboratory are aimed at:
Manufacturers of building materials
Designers and Works Management
Sector Technicians and Testers
Certification Bodies
Technical Consultants
which is offered an integral service of technical support and assistance in the fields of civil and infrastructural engineering, thanks to the execution of a wide range of tests on building materials both in the laboratory and in the field.

The high number of tests carried out mainly involves concretes, reinforcements, strands and wires, electro-welded meshes and meshes, laminated steels, bricks, elements for masonry, aggregates, bituminous conglomerates, cements and mortars, additives and mixing waters, added (fly ash , silica fume, etc.), natural stones, concrete paving stones, diagnostics of cultural heritage in the civil sector.
Petrographic surveys are performed with observation of the stereomicroscope and polarizing optical microscope, thermogravimetric analysis.
