Basics of Mixing Portland Cement: A Step-by-Step Guide
How much concrete can you make with one bag of Portland cement? You can make approximately half a 0.13m3 (4.5 ft3) of concrete with one 40 kg bag of Portland cement, or lay around 40 standard blocks. Can you add too much Portland cement to concrete? Adding excess Portland cement to concrete leads to shrinkage and cracking as it dries.

PCA EPD Portland Athena Final revised Nov2023
Portland cement is the basic ingredient of concrete. Concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden. The U.S. industry average portland cement, as found by this study, is 91.4% clinker by weight. Table 1 describes the

Portland-Limestone Cement
In cement finish milling, this results in better particle size distribution in the cement and enhanced particle packing and paste density in concrete. This is from a Canadian study where 12 different types of cement were separated into three groups: without supplementary cementitious materials (SCMs), with 35% slag cement and with 20% fly ash.
