Abstract
Super absorbent resin (SAP) is the latest product in the curing agent industry. Its
function is to reduce the risk of concrete cracking. At present, there are few researches
on sap, mainly on its structure. In this paper, the idea of inorganic organic composite
internal curing agent is proposed, which composes the inorganic material kaolin into
SAP to explore whether the inorganic material can affect the working performance of
SAP.
In this paper, the performance of cement mortar with SAP is studied in detail.
Firstly, through the performance test of sap, it can be concluded that the higher the
kaolin content, the stronger the water absorption performance of sap, but the final
water absorption equilibrium point is lower, and the rate of water absorption and loss
is slower and slower. Secondly, under the condition of fixed particle size, the factors
influencing the performance of cement mortar are comprehensively analyzed and
discussed through the combination of multi content and different kaolin content. The
drying shrinkage test results show that the content of sap and SAP have a strong effect
on the drying shrinkage of concrete, but the content of sap and SAP are different. But
under the same conditions, the two are compared. The effect on drying shrinkage is
obviously influenced by the content of high soil. The experimental results show that
the type and content of SAP affect the mechanical properties of mortar. And they are
caused by affecting the free water content and the number of holes in the mortar.
Therefore, if the content and content of SAP are more and more, the influence will be
more and more. At the early stage of hydration, sap has more influence on the
mechanical properties of mortar. In the early stage, sap has a different effect on the
flexural strength and compressive strength. Compared with the compressive strength,
sap has a greater adverse effect on the flexural strength.
