4.1 Characteristics of composite material Glassfibre reinforced concrete is a composite material for which the glassfibre has the function of a reinforcement for the cementitious matrix. The properties of the composite material as manufactured depend on: a) the properties of the matrix as base; b) the properties, geometry, quantity and orientation of the glassfibre as reinforcement; c) the bond between matrix and glassfibre; d) the manufacturing processes; e) the conditions and the treatments during production (curing). 4.2 Composition of GRC
The mechanical properties of GRC depend on the mix design and shall be consistent with the product requirements. The mix designs in Table 1 are intended as a guide; mix designs falling outside these values may be acceptable if practical experience is available and the performance has been verified before use.

Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements
SIST EN 16757:2023

This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019 and is intended to be used as a c-PCR in conjunction with that standard.
This c-PCR applies to products within the scope of CEN/TC 104 and CEN/TC 229, but it may be applicable to other concrete products until they have product specific c-PCRs.
This document applies to concrete and concrete elements for building and civil engineering, but excludes autoclaved aerated concrete and resin bound concrete. Apart from Annex G, it may be used as guidance for glass fibre reinforced concrete.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019, this document for concrete and concrete elements:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for concrete elements.
This document is intended to be used either for cradle to gate with options or cradle to grave assessment, provided the intentions are properly stated in the system boundary description.
Within the construction works context, a cradle to grave declaration delivers a more comprehensive understanding of the environmental impact associated with concrete and concrete elements.

Design and use of inserts for lifting and handling of precast concrete elements
SIST-TP CEN/TR 15728:2016

1.1   General
This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer.
The report covers commonly used applications (walls/beams/columns and solid slabs and pipes). The range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), bond failure, failure of reinforcement or failure in the steel insert.
Due to lack of information this report does not cover double shell walls, floor plates and beams for beam-and-block floor systems.
The safety levels are given for information and are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2013, 6.3) covering the insert embedment.
This Technical Report does not cover:
-   the design of the lifting inserts independently placed on the market;
-   lifting inserts for permanent and repeated use.
This Technical Report is prepared based on the fact that the anchorage in the concrete of parts of the lifting assembly is governed by the Construction Products Regulation. Lifting accessories independently placed on the market are governed by the Machinery Directive.
1.2   Types of inserts for lifting and handling
This Technical Report applies to the embedment of lifting inserts. Devices made by the precaster may consist of smooth bars, prestressing strands, steel plates with anchorage or steel wire ropes. The system devices may be e.g. internal threaded inserts, flat steel inserts and headed inserts.
Lifting loops of ribbed bars are not covered.
1.3   Minimum dimensions
This Technical Report applies in general to inserts with a minimum nominal diameter of 6 mm or the corresponding cross section. In general, the minimum anchorage depth should be hef = 40 mm.
Wire ropes of diameter less than 6 mm are not covered.

Precast concrete products - Bridge elements
SIST EN 15050:2007+A1:2012

This European Standard applies to precast concrete structural elements produced in a factory and used in bridge construction, such as deck elements.Normal weight concrete elements are considered, both reinforced and prestressed; their use can be on road bridges, railway bridges and footbridges.
Deck elements include both single elements from which the deck may be composed (beams, slabs, ribbed or cellular elements) and elements consisting of a segment of the entire deck.
Some examples of elements dealt with are shown in Annex A.
The durability aspects are also considered.
This European Standard makes reference to precast elements produced in a factory or near the construction site in a place protected from adverse weather conditions. It is assumed that if the elements are not manufactured in a factory, the production conditions assure the same level of quality control as in a factory. It is assumed that the production place is protected from rain, sunshine and wind.
Some of the elements are also treated in other European Standards (e.g. beams, slabs). This European Standard deals with the specific aspects related to the use of these elements in bridge construction.
Foundation piles, piers, abutments, barriers, bumpers, guards, arches and" box culverts are out the scope of this European Standard.

Precast concrete products - Box culverts
SIST EN 14844:2006+A2:2012

This European Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways
For the purposes of this European Standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel. This standard does not include units manufactured from autoclaved aerated concrete, nor prefabricated reinforced box culverts of lightweight concrete with open structure.
Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity.
