أي مصنع GRC يقدم منتجات عالية المقاومة؟ تحليل بيانات معتمد لأداء قوة GRC من تشينغلونغ

The strength performance of GRC products is a core reflection of their value. High-quality GRC has a flexural strength of 18-30MPa and an impact strength of 15-25kJ/㎡. Through strict quality control, Qinglong GRC maintains stable strength performance at an industry-leading level.

In the Shenzhen Yirui Biotech Building project, Qinglong GRC curtain wall panels underwent third-party testing: flexural strength reached 23MPa, exceeding the standard requirement (18MPa) by 27.8%; impact strength was 18kJ/㎡, more than 10 times that of ordinary concrete. More importantly, GRC exhibits excellent toughness characteristics, with an ultimate tensile strain of 0.3%-0.5%. This perfect combination of strength and toughness ensures better safety of components under impact loads.

Flexural Strength Performance Analysis

High-quality GRC maintains a flexural strength above 18MPa, which can reach 25-30MPa through mix proportion optimization. Strength development is reasonable, with 7-day strength reaching over 70% of the 28-day strength.

Impact Strength Characteristics

Impact strength is typically 15-25kJ/㎡, 5-8 times that of ordinary cement products. Ball drop impact tests show that a 1kg steel ball dropped freely from a height of 2m onto the panel surface causes no cracks.

Axial Compressive Strength Data

The ratio of axial compressive strength to cube compressive strength is 0.85-0.95, higher than that of ordinary concrete. This characteristic allows GRC to fully exploit its strength advantage in compression members.

Strength Stability Assessment

The strength coefficient of variation is an important indicator; high-quality products should keep it within 8%. Qinglong products maintain a strength coefficient of variation within 5%, with the coefficient of variation between batches ≤3%.

The strength performance of GRC has been verified through extensive experiments. Choosing high-quality products allows you to fully leverage their strength advantages.
