I find this reference "B.S. 12 part 2: 1971" that mentioned in some research that it is possible to use the cube of (70*70*70mm) mold, but I can not find it on the internet. can you guide me is possible to a cubic (70*70*70mm) mold to expect the compressive strength for cement mortar?
Smaller specimen means higher expected strength. It's mean about 10% higher than 150 mm cube!
Thank you very for your answer. Do you have a reference for this higher ratio?.
Also, it is cement mortar and ASTM recommended using a cube of 50 * 50 * 50 mm. But there is a cube of 70 * 70 * 70 mm in the lab. And I hope you to tell me about the standard recommended these dimensions.
Thank you very much.
Best regards.
Maybe this will help

Dear Taghreed Kh Mohammed Ali Alrekabi
You can find your answer in the following article:

Thank you very much Marko Ćećez and Mehran Shahpari for your answers.
If it is possible, I need the specification "B.S. 12 part 2: 1971" which mentions the cube of 70 * 70 * 70 mm dimensions.
Best regards.
HELLO , using 7 *7*7 cm cubes is correct
you can read :الدليل الاسترشادي المرجعي رقم 198 لسنة 1999 الصادر من جامعة بابل بهذا اللنك مع التقدير والتوفيق لكم

In the recommended Chinese Construction Engineering Industry Construction Standard JGJ/T 70-2009 "Standard for test method of basic properties of construction mortar", it is stated that the specimen size for the cubic compressive strength test of cement mortar is 70.7mm*70.7mm*70.7mm. You can use it as a reference, but unfortunately this standard is only available in Chinese, not in English.
Thank you very much Qusay Abdulhameed Jabal for your answer. Is الدليل الاسترشادي المرجعي رقم 198 لسنة 1999 this Iraqi specification? and is it acceptable for international publication?
Thank you very much Haochen Wang for your answer. Can you send me this specification? I will translate it by google translate.
yes you can use it as reference
but also there is another reference which is a book called "tests in concrete technology" by Dr. Hana Abid Yousif , Ministry of Higher Education , Iraq ,handbook for civil engineering students cement tests p.p-1-10 , with best wishes-- this reference use 7*7*7 cm cubes for testing compressive strength for cement mortar... thank u
Sure, of course can. The attachment is the specific document of this recommended standard. You can translate Part 9 (pages 17-19) in a targeted manner. This part is your most concerned "Cubic Cement Mortar Compressive Strength Test". Taghreed Kh Mohammed Ali Alrekabi
Thank you very much Qusay Abdulhameed Jabal, can you send me this book of Dr. Hana Abid Yousif, where she was my teacher in the Technology university. But I do not have this book. Best regards.
Thank you very much Haochen Wang for share with me this standard. Best regards
