How to Select Macro Synthetic Fibers for Concrete Projects: A Procurement Checklist

Selecting macro synthetic fibers starts with the project specification, construction process and required documentation. A useful procurement process gives suppliers the same project information and compares their proposals against the same acceptance requirements.

This checklist is intended for ready-mix producers, precast manufacturers, flooring contractors and project procurement teams preparing a product enquiry or evaluating quotations.

1. How to Select Macro Synthetic Fibers for Your Project

Understanding how to select macro synthetic fibers starts with the project specification, construction process and required documentation. This procurement checklist helps concrete producers, contractors and buyers prepare consistent enquiries, review supplier submissions and compare quotations against clearly defined project requirements.

Application	Information to include in the enquiry
Concrete floors and slabs	Specification reference, placement method, finishing requirements and reinforcement arrangement
Precast concrete	Component type, production process, placement method and project acceptance requirements
Ready-mix supply	Intended end use, batching process, transport conditions and site placement method
Shotcrete	Project specification, application process, equipment constraints and required approval documents

These details help define the enquiry. They do not establish that a particular fiber or dosage is suitable.

If a requirement has not yet been defined, identify it as open rather than asking suppliers to assume it.

2. Prepare a Consistent Enquiry Package

Send each shortlisted supplier the same information:

• Project country and delivery destination.

• Application and relevant specification sections.

• Required performance evidence and approval procedure.

• Available concrete mixture and construction information.

• Proposed project schedule and purchasing quantity.

• Packaging, shipment and delivery requirements.

State whether the enquiry concerns an existing specified product, an alternative product submission or an initial material assessment. These are different purchasing situations and may require different supporting documents.

Do not describe an alternative as approved before the project’s review process is complete.

3. Request Documentation for the Exact Product

Ask the supplier to identify the proposed product clearly and connect each document to that product.

A practical submission package may include the current product data sheet, relevant test reports, handling instructions and the information required by the project specification.

Check the scope of the evidence:

• Does the report name the proposed product?

• Does it identify the tested dosage and concrete conditions?

• Does it address the measurements required by the specification?

• Are any limitations or application conditions stated?

• Is the submitted document revision clear?

A brochure, a test report and a project approval serve different purposes. Keep them separate in the procurement record.

4. Arrange Technical Review and Construction Trials

The responsible project professionals should review technical suitability and any proposed reinforcement change.

Procurement can support that process by maintaining a clear record of the proposed product, submitted documents, outstanding questions and approval status.

Where a construction trial is required, agree its scope before ordering trial material. Record the product, mixture, mixing procedure, equipment and acceptance criteria.

The trial should address the actual construction questions. For example, a pumping concern requires evidence relevant to the proposed pumping arrangement; a finishing concern requires an appropriate placement and finishing assessment.

A supplier recommendation remains a proposal until the required review and acceptance steps have been completed.

5. Compare Quotations on a Consistent Basis

Price per kilogram alone does not describe the full purchasing decision.

Compare quotations using the same approved or proposed basis, clearly marking any assumptions that remain unresolved.

Quotation item	What to record
Product identity	Exact product name and document revision
Proposed usage basis	Dosage and approval status, where applicable
Supply scope	Quantity, packaging and included items
Delivery	Destination, trade terms and stated lead time
Documentation	Reports and project submission support included
Trial requirements	Material, transport and site arrangements
Commercial terms	Currency, quotation validity and payment terms

If different proposals use different dosages or performance assumptions, show those differences explicitly. Do not turn an unapproved assumption into a claimed cost saving.

Any installed-cost comparison should use documented project inputs for material, logistics, handling and construction activities.

6. Keep Approval and Purchasing Records Connected

Before placing the production order, confirm that the product in the purchase order matches the reviewed submission.

Record any conditions attached to approval. If the product, mixture, construction process or relevant project requirement changes, refer the change through the applicable review procedure.

This helps prevent a technically reviewed proposal from becoming a different product or application during purchasing.

Frequently Asked Questions

Should I choose embossed or twisted fiber first?

Start with the project requirements. Geometry can help identify options, but selection requires product-specific evidence and an appropriate approval process.

Can I request a quotation before the dosage is approved?

Yes. Ask the supplier to state the quotation basis and mark unresolved technical inputs clearly. Treat the price as provisional where those inputs affect the final order.

What should I send PIONEER for an initial enquiry?

Send the application, destination, specification reference, purchasing quantity and available construction information. Identify which requirements are confirmed and which remain open.
