Grading - Important to the workability of fresh concrete The grading or particle size distribution of an aggregate is determined by a sieve analysis When we are empowered to make our own decision and act for ourselves we take a more personal interest in our...

High Density Concrete Types and Properties Concrete

Aggregates to be Used in Shielding High Density Concrete For making shielding concrete heavy weight aggregate having a specific gravity between 35 to 40 is needed There are many aggregates whose specific gravity is more than 35 for making a heavy weight concrete Some of natural commercially used aggregates are as follows 1 Barite 2...

Classification of Aggregates Based on Size and Shape

Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage Aggregates occupy 70 to 80 of total volume of concrete So we can say that one should know definitely about the aggregates in depth to study more about concrete Classification of Aggregates as per Size and Shape...

Properties of Concrete with Coconut Shells as Aggregate

The concretes were mixed in a planetary mixer of 100 l capacity The mixing time kept to about 3 to 4 min Mixing of the materials was in a sequence i portion of design water poured into mixture drum ii cement gently placed and iii aggregate and CS was spread over the cement and started mixing During mixing the remaining design water was...

principles of concrete mix designppt

Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened stat In general concrete mixes are designed in order to achieve a defined workability strength and durability The selection and proportioning of materials depend on 34...

The Secret of Preplaced Aggregate Concrete

Conventional concrete is placed as a composite aggregate and cement-grout mixture This means the aggregate and cementitious grout components are combined before the concrete is placed into formwork PAC is different than conventional concrete methods because its components are placed in separate steps Like the name implies the aggregates are...
