How to Read a Cement Bag: OPC PCC PPC, SNI Mark and Weight

如何读水泥袋标签：OPC/PCC/PPC、SNI标志与净重

How to read a cement bag matters more than picking a brand by colour. The sack prints the type (OPC/PCC/PPC), SNI number, net weight, brand, and—under the new rule—an electronic mark as well. Reading the label correctly avoids the wrong type for plaster versus structural concrete and helps reject bags without mandatory certification. This article focuses on reading the pack, not repeating a full cement-types guide.

Key Facts

How to read cement bag step 1: find the type

Look for large text such as Portland Composite / PCC, Portland Cement / OPC, or Portland Pozzolan / PPC. JakartaBuilding lists the codes most often seen in stores: PCC for general building and plaster, OPC Type I for general concrete without special requirements, OPC Types II/V for sulphate soils (often big-bag/bulk, not small sacks), plus PPC and slag when the job specifies them.

Do not rely on sack colour alone when you learn how to read cement bag marks. Match the type wording to the nearby SNI number.

Step 2: match the SNI number

  • OPC / Portland cement → SNI 2049-1:2020
  • PCC / Portland composite → SNI 7064:2022
  • PPC / Portland pozzolan → SNI 0302:2014

Permenperin 26/2024 also mandates SNI for white cement (129:2018), masonry (3758:2024), slag (8363:2023) and hydraulic cement (8912:2020). If a sack still shows an older edition while stock is new, ask the seller or photograph the label—editions change and marking must stay consistent with a valid certificate.

Step 3: check the SNI mark and electronic mark

Article 28 of Permenperin 26/2024: cement that already has an SNI Certificate must carry the SNI mark and an electronic mark (link to certificate data in SIINas) after SPPT SNI is granted. Bags missing both deserve scrutiny. JakartaBuilding notes the tighter rule requires both marks on the seven mandatory cement types.

Step 4: read net weight and bag condition

The binding figure is the printed net weight, not a hand estimate. Tokban cites SNI 7064: net bag weight 25, 40 or 50 kg; retail PCC is often 40 kg (easier to lift) or 50 kg (tonnage projects). Semen Baturaja adds that labels also carry storage advice, mix guidance and safety instructions; production codes help if a complaint arises.

Reject or photograph first any torn, wet or hard-lumped sack—cement that has already taken up moisture will not perform fully.

Quick checklist before you pay

  1. Type clearly printed (PCC/OPC/PPC/etc.) matches the job.
  2. SNI number matches the type above.
  3. SNI mark + electronic mark present (or a clarified transition stock under Art. 53).
  4. Printed net weight (25/40/50 kg) matches the order.
  5. Bag intact, not lumped; ask for fresh stock (FIFO).
