# How do you check delivered cement bags for lumps in Somaliland? > Open, feel and weigh bags on arrival, record the batch, and reject bags that have set before they reach the mixer. - By: Editorial Team, Somali Construction Review (https://somaliconstructionreview.com/about) - Published: 30 October 2026 - Format: Practical guide (general practice) - Publication: Somali Construction Review (https://somaliconstructionreview.com) - Subject: Materials - Place: Somaliland - Tags: somaliland, cement, materials, material-testing - Web version: https://somaliconstructionreview.com/blog/check-cement-bags-lumps-somaliland ## Key points - Lumps that resist finger pressure mean the cement has taken up moisture and should not go into structural concrete. - Record bag weight, batch number and delivery date on a receiving sheet before the bags go into the store. - Ask the supplier for the batch test certificate and keep it with the delivery record. Cement bags that have set into hard lumps have already absorbed moisture, and those lumps will not break down in the mixer. Check every delivery at the vehicle: look for torn or damp bags, feel for lumps through the paper, then open one bag from each batch and squeeze the cement in your hand. Loose, cool powder passes. Hard lumps fail. ## What do you look for before the bags leave the truck? Look at the bag wrapper and the truck bed first. Bags sitting on a wet floor, stacked against a damp wall or showing water stains have had contact with moisture, and the cement inside can be partly hydrated even when the paper looks sound. Do the check in this order: - Count the bags against the delivery note and note any shortfall. - Look for tears, stains, hardened corners and bags that have flattened under weight. - Push the flat of your hand into the middle of a stack. Cement that has set feels like a solid block. - Open one bag from each batch number. Powder should run freely between the fingers. - Squeeze a sample. Lumps that crumble under light pressure may only be compaction from stacking. Lumps that resist finger pressure have hydrated and the bag should be set aside. Record the batch number, the delivery date, the supplier and the number of bags rejected on a receiving sheet. Write the batch on the store board so the storekeeper issues older stock first. The [materials](/topics/materials) section of this publication covers the wider receiving routine, and [How do you check delivery paperwork for materials in Puntland?](/blog/check-delivery-paperwork-materials-puntland) sets out what the papers should show. ## How do you test a bag once it is in the store? A simple field check is a small pat of cement mixed with water and left to set. A sound sample sets hard within a day and breaks with a sharp edge. A sample that stays soft, crumbles, or sets unevenly points to a bag that has taken up moisture. Weighing tells you less than people expect. A bag can weigh close to its stated mass and still contain set material, because the water that hydrated it is still inside. Use weight to catch short fills and torn bags, not to prove the cement is good. Ask the supplier for the batch test certificate and file it with the delivery note. [How do you check a supplier's test certificate in Somaliland?](/blog/check-supplier-test-certificate-somaliland) explains the fields to read. Where a delivery matters for structural concrete, ask a laboratory for its rate on a setting time and fineness check, and compare that against the certificate. Confirm any acceptance limit against the project specification or the engineer, not against a rule of thumb picked up on site. > **Warning:** Do not break up set lumps and mix them back in. The hardened material will not hydrate again and it weakens the concrete around it. ## What do you do with cement that has started to set? Set or lumpy cement should not go into reinforced concrete, columns, beams or slabs. Use it, if at all, only where the engineer agrees the strength demand is low, such as a non-structural blinding layer, and record the decision. When a delivery fails the check: - Segregate the bags and mark them clearly so nobody issues them by mistake. - Photograph the bags and the delivery note before the vehicle leaves. - Tell the supplier in writing the same day and ask for replacement from a different batch. - Read your contract to see what it says about rejected material and replacement before you agree anything on payment. - Log the rejection in the site diary with the batch number, so the record shows which cement went into which pour. If several bags from one batch fail, treat the whole batch as suspect. Ask the supplier where it was made and when, and compare it with the certificate.

Use it on the next delivery, open one bag per batch in front of the driver, and file the sheet with the batch certificate. That sheet becomes your evidence if a pour is later questioned. ## Questions ### Can you use cement with a few soft lumps? Soft lumps that crumble under finger pressure are usually compaction from stacking and the cement can be used. Hard lumps that resist pressure mean the cement has hydrated and those bags should be segregated and reported to the supplier. ### Does a full bag weight prove the cement is good? No. Hydrated cement still carries the water that set it, so the bag can weigh close to its stated mass. Use weight to catch short fills and torn bags, and check the powder by feel and by a small set test. ## Sources - [How do you check a supplier's test certificate in Somaliland?](https://somaliconstructionreview.com/blog/check-supplier-test-certificate-somaliland) - [How do you compare two cement brands for the same Puntland job?](https://somaliconstructionreview.com/blog/compare-two-cement-brands-puntland) - [Concrete calculator (Somali Construction Review)](https://somaliconstructionreview.com/concrete-calculator) - [Construction material calculator (Somali Construction Review)](https://somaliconstructionreview.com/construction-material-calculator)
